Only remaining users are ixgbe, sch_teql, gianfar & macvlan : 1) ixgbe can be converted to use existing tx_ring counters. 2) macvlan incremented txq->tx_dropped, it can use the dev->stats.tx_dropped counter. 3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats) Now we have ndo_get_stats64(), use it, even for "unsigned long" fields (No need to bring back a struct net_device_stats) 4) gianfar adds a stats structure per tx queue to hold tx_bytes/tx_packets This removes a lockdep warning (and possible lockup) in rndis gadget, calling dev_get_stats() from hard IRQ context.

* vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross2010-10-211-2/+2
| | | | | | | | | | | | | Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.

Currently before queuing skb into the rx_recycle it is "un-skb_reserve"-ed so when taken out in gfar_new_skb() it wont be reserved twice. This patch makes sure the alignment skb_reserve is done once, upon allocating the skb and not when taken out of the rx_recycle pool. Eliminating the need to undo anything before queue skb back to the pool. NOTE: This patch will compile and is fairly straight forward but I do not have environment to test it as I did with the 2.6.32.15 fix.

Any subsequent receive frame that is larger than two bytes will reset the state so the graceful stop can complete. A MAC receiver (Rx) reset will also reset the state." This patch implements the proposed workaround: "If IEVENT[GRSC] is still not set after the timeout, read the eTSEC register at offset 0xD1C. If bits 7-14 are the same as bits 23-30, the eTSEC Rx is assumed to be idle and the Rx can be safely reset. If the register fields are not equal, wait for another timeout period and check again."

This throttling threshold is supposed to trigger only when the controller has sufficient data to keep transmit active for the duration of the memory fetches. The state machine handling this threshold, however, fails to take large TOE frames into account. As a result, TOE=1 frames larger than 2500 bytes often see excess delays before start of transmission." This patch implements the workaround as suggested by the errata document, i.e.: "Limit TOE=1 frames to less than 2500 bytes to avoid excess delays due to memory throttling. When using packets larger than 2700 bytes, it is recommended to turn TOE off." To be sure, we limit the TOE frames to 2500 bytes, and do software checksumming instead.

The controller also erroneously marks RxBD[TR]=1 if the received frame length is MAXFRM or MAXFRM-1, even though those frames are not truncated. No truncation or truncation error occurs if MACCFG2[Huge Frame]=1." There are two options to workaround the issue: "1. Set MACCFG2[Huge Frame]=1, so no truncation occurs for invalid large frames. Software can determine if a frame is larger than MAXFRM by reading RxBD[LG] or RxBD[Data Length]. 2. Set MAXFRM to 1538 (0x602) instead of the default 1536 (0x600), so normal-length frames are not marked as truncated. Software can examine RxBD[Data Length] to determine if the frame was larger than MAXFRM-2." This patch implements the first workaround option by setting HUGEFRAME bit, and gfar_clean_rx_ring() already checks the RxBD[Data Length].

This situation confuses the driver, and so the skb_put() sanity check fails. This patch fixes the issue by adding an appropriate check, i.e. the driver should not try to process frames with buffer descriptor's length over rx_buffer_size (i.e. maxfrm and mrblr). Note that sometimes eTSEC works correctly, i.e. in the second (last) buffer descriptor bits 'truncated' and 'crcerr' are set, and so there's no oops.

With this patch the bit will only be set if requested from user space with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is disabled during normal operation. Users who are not interested in time stamps will not experience problems with buggy CPU revisions or performance drops any more. The setting of TMR_CTRL[TE] is still up to the user. This is considered safe because users wanting HW timestamps must initialize the eTSEC clock first anyway, e.g. with the recently submitted PTP clock driver.

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

| * drivers/net: Remove unnecessary returns from void function()sJoe Perches2010-05-141-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand. Compile tested x86 allmodconfig only. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size for skbs which is added to the recycled list is using the current descriptor size which is current MTU. gfar_new_skb() is also using this size. So after changing or alteast increasing the MTU all recycled skbs should be dropped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | gianfar driver may pass NULL pointer to the of_translate_address(), which may lead to a kernel oops.

| * | gianfar: Add hardware TX timestamping supportManfred Rudigier2010-04-131-19/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a packet has the skb_shared_tx->hardware flag set the device is instructed to generate a TX timestamp and write it back to memory after the frame is transmitted. During the clean_tx_ring operation the timestamp will be extracted and copied into the skb_shared_hwtstamps struct of the skb. TX timestamping is enabled by setting the tx_type to something else than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only supported by eTSEC devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device is configured to insert hardware timestamps into all received packets. The RX timestamps are extracted from the padding alingment bytes during the clean_rx_ring operation and copied into the skb_shared_hwtstamps struct of the skb. This extraction only happens if the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with the SIOCSHWTSTAMP ioctl command. Hardware timestamping is only supported for eTSEC devices. To indicate device support the new FSL_GIANFAR_DEV_HAS_TIMER flag was introduced. Signed-off-by: Manfred Rudigier <manfred.rudigier@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.
