      bnx2: Use request_firmware() · 57579f76
      由 Michael Chan 提交于 
      Based on original patch by Ben Hutchings <ben@decadent.org.uk> and
Bastian Blank <waldi@debian.org>, with the following main changes:

Separated the mips firmware and rv2p firmware into different files
to make it easier to update them separately.

Added some code to fixup the rv2p code with run-time information
such as PAGE_SIZE.

Update version to 2.0.0.

I don't know if this is related, but the following patch seems to fix some DMA
mapping bug. Can somebody comment who does understand the code better than me?

      virtio_net: Set the mac config only when VIRITO_NET_F_MAC · 62994b2d
      由 Alex Williamson 提交于 
      VIRTIO_NET_F_MAC indicates the presence of the mac field in config
space, not the validity of the value it contains.  Allow the mac to be
changed at runtime, but only push the change into config space with the
VIRTIO_NET_F_MAC feature present.

      e1000: fix loss of multicast packets · 81c52285
      由 Jesse Brandeburg 提交于 
      e1000 (and e1000e, igb, ixgbe, ixgb) all do a series of
operations each time a multicast address is added.  The flow goes
something like

1) stack adds one multicast address
2) stack passes whole current list of unicast and multicast
   addresses to driver
3) driver clears entire list in hardware
4) driver programs each multicast address using iomem in a loop

This was causing multicast packets to be lost during the
reprogramming process.

reference with test program:
http://kerneltrap.org/mailarchive/linux-netdev/2009/3/14/5160514/thread

Thanks to Dave Boutcher for his report and test program.

This driver fix prepares an array all at once in memory and
programs it in one shot to the hardware, not requiring an "erase"
cycle.
