| * | net_sched: factorize qdisc stats handlingEric Dumazet2011-01-1024-72/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HTB takes into account skb is segmented in stats updates. Generalize this to all schedulers. They should use qdisc_bstats_update() helper instead of manipulating bstats.bytes and bstats.packets Add bstats_update() helper too for classes that use gnet_stats_basic_packed fields. Note : Right now, TCQ_F_CAN_BYPASS shortcurt can be taken only if no stab is setup on qdisc. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | cxgb4vf: fix mailbox data/control coherency domain raceCasey Leedom2011-01-101-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the VFs, the Mailbox Data "registers" are actually backed by T4's "MA" interface rather than PL Registers (as is the case for the PFs). Because these are in different coherency domains, the write to the VF's PL-register-backed Mailbox Control can race in front of the writes to the MA-backed VF Mailbox Data "registers". So we need to do a read-back on at least one byte of the VF Mailbox Data registers before doing the write to the VF Mailbox Control register.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver is reading flash fw version from defined address, this address may be invalid. Indeed Driver should read address for fw version through flash layout table. Flash layout table has defined region and address for fw version address should be read from fw image region. Driver has check for old firmware, this bug can cause driver load fail. This patch will try to read fw version from flash image region, if that fails, read from defined address.

| * ixgbe: update ntuple filter configurationAlexander Duyck2011-01-095-371/+250
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

| * ixgbe: further flow director performance optimizationsAlexander Duyck2011-01-094-44/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

| * e1000e: power off PHY after reset when interface is downBruce Allan2011-01-093-35/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Phys supported by the driver do not remain powered off across a reset of the device when the interface is down, e.g. on 82571, but not on 82574. This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics. A couple minor whitespace issues were cleaned up, too.

| | | | | | | | | | | | | | | | | | | | | | In order to compute the features for other offloads (primarily scatter/gather), we need to first check the ability of the NIC to offload the checksum for the packet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This switches skb_need_linearize() to use the features that have been centrally computed. In doing so, this fixes a problem where scatter/gather should not be used because the card does not support checksum offloading on that type of packet. On device registration we only check that some form of checksum offloading is available if scatter/gatther is enabled but we must also check at transmission time. Examples of this include IPv6 or vlan packets on a NIC that only supports IPv4 offloading. Signed-off-by: Jesse Gross <jesse@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netif_get_vlan_features() is currently only used by netif_needs_gso(), so it only concerns itself with GSO features. However, several other places also should take into account the contents of the packet when deciding whether to offload to hardware. This generalizes the function to return features about all of the various forms of offloading. Since offloads tend to be linked together, this avoids duplicating the logic in each location (i.e. the scatter/gather code also needs the checksum logic).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.

Failure to call release_firmware() will result in memory leak in drivers/atm/ambassador.c::ucode_init(). This patch makes sure we always call release_firmware() when needed, thus removing the leak(s). Yes, I know checkpatch complains about this patch, but it was either that or completely mess up the existing style, so I opted to use the existing style and live with the checkpatch related flak.

| * | net/fec: add dual fec support for mx28Shawn Guo2011-01-093-21/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add mx28 dual fec support. Here are some key notes for mx28 fec controller. - The mx28 fec controller naming ENET-MAC is a different IP from FEC used on other i.mx variants. But they are basically compatible on software interface, so it's possible to share the same driver. - ENET-MAC design on mx28 made an improper assumption that it runs on a big-endian system. As the result, driver has to swap every frame going to and coming from the controller. - The external phys can only be configured by fec0, which means fec1 can not work independently and both phys need to be configured by mii_bus attached on fec0. - ENET-MAC reset will get mac address registers reset too. - ENET-MAC MII/RMII mode and 10M/100M speed are configured differently FEC. - ETHER_EN bit must be set to get ENET-MAC interrupt work.

On i.mx fec, interrupt can be triggered even bit ETHER_EN of ECR register is not set. But on mx28 fec, ETHER_EN must be set to get interrupt work. Meanwhile, MII interrupt is mandatory to resume the driver, because MDIO read/write changed to interrupt mode by commit below. 97b72e4320a9aaa4a7f1592ee7d2da7e2c9bd349 fec: use interrupt for MDIO completion indication fec_restart/fec_stop comes out as the solution working for both cases.
