1) Forgotten counter incrementation in sis900_rx() in case
it doesn't get memory for skb, that leads to whole interface failure.
Problem is accompanied with messages:
eth0: Memory squeeze,deferring packet.
eth0: NULL pointer encountered in Rx ring, skipping2) If counter cur_rx overflows and there'll be temporary memory problems
buffer can't be recreated later, when memory IS available.3) Limit the work in handler to prevent the endless packets processing
if new packets are generated faster then handled.Signed-off-by: Konstantin Khorenko

Add MAINTAINER entry for the new PPC4xx EMAC driver
Signed-off-by: Eugene Surovegin
Signed-off-by: Jeff Garzik -
This patch replaces current PowerPC 4xx EMAC driver with
new, re-written from the scratch version. This patch is quite big
(~234K) because there is virtualy 0% of common code between old and
new version.New driver uses NAPI, it solves stability problems under heavy packet
load and low memory, corrects chip register access and fixes numerous
small bugs I don't even remember now.This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.Signed-off-by: Eugene Surovegin

Under heavy PCI bus load, ports of the DFE-580TX 4-ethernet port board stop
working, with currently no other cure than a powercycle. Here is a tested
fix. By the way, I also fixed some references and attribution.Signed-off-by: Philippe De Muyter

Here is a patch that changes the way the MAC filter is computed for the
multicast addresses. The computation is taken from the SiS GPL driver.This patch is necessary to get IPv6 working.

prism54 is leaking information when passing transmits to the firmware.
There is no requirement to adjust the length to >= ETH_ZLEN.
Just pass the skb length (after possible adjustment).Signed-off-by: Roger While

This patch fixes a bug that happens when the hypervisor can't add a
buffer. The old code wrote IBM_VETH_INVALID_MAP into the free_map
array, so next time the index was used, a ibmveth_assert() caught it and
called BUG(). The patch writes the right value into the free_map array
so that the index can be reused.Signed-off-by: Santiago Leon

This patch adds the lockless TX feature to the ibmveth driver. The
hypervisor has its own locking so the only change that is necessary is
to protect the statistics counters.Signed-off-by: Santiago Leon

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.

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: Santiago Leon

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: Michael Chan

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: Michael Chan
