This patch removes the allocation of RX skb's buffers from a workqueue to be called directly at RX processing time. This change was suggested by Dave Miller when the driver was starving the RX buffers and deadlocking under heavy traffic: > Allocating RX SKBs via tasklet is, IMHO, the worst way to > do it. It is no surprise that there are starvation cases. > > If tasklets or work queues get delayed in any way, you lose, > and it's very easy for a card to catch up with the driver RX'ing > packets very fast, no matter how aggressive you make the > replenishing. By the time you detect that you need to be > "more aggressive" it is already too late. > The only pseudo-reliable way is to allocate at RX processing time. > Signed-off-by:

This patch changes the way the ibmveth driver handles the receive buffers. The old code mallocs and maps all the buffers in the pools regardless of MTU size and it also limits the number of buffer pools to three. This patch makes the driver malloc and map the buffers necessary to support the current MTU. It also changes the hardcoded names of the buffer pool number, size, and elements to arrays to make it easier to change (with the hope of making them runtime parameters in the future). Signed-off-by:

This patch updates dev->trans_start and dev->last_rx so that the ibmveth driver can be used with the ARP monitor in the bonding driver. Signed-off-by:

Change the ASF heart beat to 5 seconds for faster detection of system crash. The driver sends the heartbeat every 2 seconds and the ASF firmware will timeout and reset the device if no heartbeat is received after 5 seconds. The old scheme of 2 minutes is ineffective. tg3_write_mem_fast() is added to speed up the IO to send the heartbeat. When no workaround is needed, it will use direct MMIO to memory space to write to memory. Signed-off-by:

Add complete support for 5714/5715. These chips are very similar to 5780 so the changes are very trivial. A TG3_FLG2_5780_CLASS flag is added to identify these chips. Signed-off-by:

- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

Beginning of gfp_t annotations: - -Wbitwise added to CHECKFLAGS - old __bitwise renamed to __bitwise__ - __bitwise defined to either __bitwise__ or nothing, depending on __CHECK_ENDIAN__ being defined - gfp_t switched from __nocast to __bitwise__ - force cast to gfp_t added to __GFP_... constants - new helper - gfp_zone(); extracts zone bits out of gfp_t value and casts the result to int Signed-off-by:
