[Ben Hutchings <bhutchings@solarflare.com>]

The following changes since commit defb3519a64141608725e2dac5a5aa9a3c644bae:

  net: Abstract away all dst_entry metrics accesses. (2010-12-09 10:46:36 -0800)

are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next-2.6.git for-davem

These changes include the 'TX push' feature I mentioned at netconf.
When an TX queue is empty this feature allows the driver to write the
next DMA descriptor directly to the NIC, reducing latency by about 0.5
us (dependent on the system).
