* forcedeth: Improve stats countersMandeep Baines2011-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Rx byte count was off; instead use the hardware's count. Tx packet count was counting pre-TSO packets; instead count on-the-wire packets. Report hardware dropped frame count as rx_fifo_errors. - The count of transmitted packets reported by the forcedeth driver reports pre-TSO (TCP Segmentation Offload) packet counts and not the count of the number of packets sent on the wire. This change fixes the forcedeth driver to report the correct count. Fixed the code by copying the count stored in the NIC H/W to the value reported by the driver. - Count rx_drop_frame errors as rx_fifo_errors: We see a lot of rx_drop_frame errors if we disable the rx bottom-halves for too long. Normally, rx_fifo_errors would be counted in this case. The rx_drop_frame error count is private to forcedeth and is not reported by ifconfig or sysfs. The rx_fifo_errors count is currently unused in the forcedeth driver. It is reported by ifconfig as overruns. This change reports rx_drop_frame errors as rx_fifo_errors.

* forcedeth: remove unneeded stats updatesdavid decotigny2011-11-071-34/+1
| | | | | | | | | | | | | | Function ndo_get_stats() updates most of the stats from hardware registers, making the manual updates un-needed. This change removes these manual updates. Main exception is rx_missed_errors which needs manual update. Another exception is rx_packets, still updated manually in this commit to make sure this patch doesn't change behavior of driver. This will be addressed by a future patch. Signed-off-by: David Decotigny <david.decotigny@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | When forcedeth module is unloaded, there exists a path that can lead to mod_timer() after del_timer_sync(), causing an oops. This patch short-circuits this unneeded path, which originates in nv_get_ethtool_stats().

* sky2: fix regression on Yukon Optimastephen hemminger2011-11-041-11/+0
| | | | | | | | | | | | | | Changes to support other Optima types, introduced an accidental regression that caused 88E8059 to come up in 10Mbit/sec. The Yukon Optima supports a reverse auto-negotiation feature that was incorrectly setup, and not needed. The feature could be used to allow wake-on-lan at higher speeds. But doing it correctly would require other changes to initialization. Reported-by: Pavel Mateja <pavel@netsafe.cz> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

* macvlan: receive multicast with local addressstephen hemminger2011-11-041-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | When implementing VRRP v2 using macvlan several problems were discovered. VRRP is weird in that all routers participating in a redundant group use the same virtual MAC address. Macvlan is a natural driver to use for this but it doesn't work. The problem is that packets with a macvlan device's source address are not received. The problem is actually a regression that date back almost 2 years now. The original problems started with: commit 618e1b7482f7a8a4c6c6e8ccbe140e4c331df4e9 Author: Arnd Bergmann <arnd@arndb.de> Date: Thu Nov 26 06:07:10 2009 +0000 macvlan: implement bridge, VEPA and private mode This patches restores the original 2.6.32 behavior.

* tg3: Eliminate timer race with reset_taskMatt Carlson2011-11-042-13/+2
| | | | | | | | | | | | | | During shutdown, it is impossible to reliably disable the timer and reset_task threads. Each thread can schedule the other, which leads to shutdown code that chases its tail. To fix the problem, this patch removes the ability of tg3_reset_task to schedule a new timer thread. To support this change, tg3_timer no longer terminates itself, but rather goes into a polling mode.

* tg3: Schedule at most one tg3_reset_task runMatt Carlson2011-11-042-9/+25
| | | | | | | | | | | | | | | | | It is possible for multiple threads in the tg3 driver to each attempt to schedule a run of tg3_reset_task(). The multiple tg3_reset_task executions could all wind up on the same queue (and execute serially) or wind up on the queues of another processor (which could execute in parallel). Either scenario is not what was truly desired. This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to determine whether or not to schedule another run of tg3_reset_task(). With the new flag comes two new functions to facilitate scheduling and descheduling of tg3_reset_task().

| | | | | | | | | | | | | | The new 4k tx bd segmentation code had a bug in the error cleanup path. If the driver did not map all the physical fragments, the abort path would wind up advancing the producer index beyond the point where the setup code stopped. This would ultimately turn into a tx recovery error where the driver would expect the skb pointer to be set when it isn't.

For other cases, each function is assigned its own request and grant bits of a single register. For the latter cases, the tg3 driver is incorrectly allowing each function to use the same set of grant / request bits. This patch fixes the code so that each function uses the appropriate bitset.

However, it assumes that the scan request was allocated via the cfg80211 stack. Libertas has its own internal allocation method, kept track of with priv->internal_scan. This doesn't set scan_req->wiphy, amongst other things, which results in hitting a BUG() when we call cfg80211_scan_done on the request. This provides a function to take care of the low-level scan_req cleanup details. We simply call that to deal with finishing up scan requests.

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

On 64-bit platforms this allocates twice more than required. Fix this by allocating the correct size for the type. This is the same bug just fixed in mlx4 by Eli Cohen <eli@mellanox.co.il>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current driver never does DMA unmapping on these buffers. Fix that by adding DMA unmapping to the task cleanup callback, and DMA mapping to the task init function (drop the headers_initialized micro-optimization).

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each.

The code does use a RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems to be a way to keep both. (The easiest way out would be to rip out both the Kconfig symbol and the macro.) Note there's also a module parameter 'use_xtal' to influence all this.
