David S. Miller [Mon, 13 Dec 2010 05:55:08 +0000]
ipv4: Don't pre-seed hoplimit metric.

Always go through a new ip4_dst_hoplimit() helper, just like ipv6.

This allowed several simplifications:

1) The interim dst_metric_hoplimit() can go as it's no longer
   userd.

2) The sysctl_ip_default_ttl entry no longer needs to use
   ipv4_doint_and_flush, since the sysctl is not cached in
   routing cache metrics any longer.

3) ipv4_doint_and_flush no longer needs to be exported and
   therefore can be marked static.

When ipv4_doint_and_flush_strategy was removed some time ago,
the external declaration in ip.h was mistakenly left around
so kill that off too.

We have to move the sysctl_ip_default_ttl declaration into
ipv4's route cache definition header net/route.h, because
currently net/ip.h (where the declaration lives now) has
a back dependency on net/route.h

drivers/net: don't use flush_scheduled_work()

flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.

with 127+1.  This results in the possibility of the value being set

e1000e: 82579 PHY incorrectly identified during init

During init, reading the 2 PHY ID registers back-to-back in the default
fast mode could return invalid data (all F's) and in slow mode could
return data to the second read the data from the first read.  To resolve

resolve the issue in slow mode, put in a delay for every 82579 PHY access.
Since this PHY is currently only paired with the pch2lan MAC and the PHY
type is not known before the first PHY access which can fail this way,
check for this based on MAC-type.

enic: Add ndo_set_vf_mac support for enic dynamic devices

This patch implements the ndo_set_vf_mac netdev operation for enic
dynamic devices. It treats the mac address set by IFLA_VF_MAC as a
special case to use it in the port profile provisioning data.

8 years agopktgen: adding prefetchw() call
Junchang Wang [Wed, 8 Dec 2010 16:55:16 +0000]
pktgen: adding prefetchw() call

We know for sure pktgen is going to write skb->data right after
*_alloc_skb, causing unnecessary cache misses.

Idea is to add a prefetchw() call to prefetch the first cache line
indicated by skb->data. On systems with Adjacent Cache Line Prefetch,
it's probably two cache lines are prefetched.

With this patch, pktgen on Intel SR1625 server with two E5530
quad-core processors and a single ixgbe-based NIC went from 8.63Mpps
to 9.03Mpps, with 4.6% improvement.
