Alright, here's the bugfix series [7 patches]. There's one sparse
annotation patch besides this, I will submit it seprarately if
bugfix windows allows that.

[PATCHv2 2/7] netxen: fix ipv6 offload and tx cleanup

[Dhananjay Phadke]

o fix the ip/tcp hdr offset in tx descriptors for ipv6.
o cleanup xmit function, move the tso checks into separate function,
  this reduces unnecessary endian conversions back and forth.
o optimize macros to initialize tx descriptors.

[PATCHv2 4/7] netxen: firmware init fix

[Dhananjay Phadke]

o Fix order or rom register writes.
o Reduce udelays when writing rom registers.

This cuts the firmware init time by 40%.

o Do not reset core/memory clocks when reinitializing driver.
  Firmware willl handle this when initialized.

[PATCHv2 5/7] netxen: cleanup mac list on driver unload

[Dhananjay Phadke]

This fixes a tiny memory leak when driver is unloaded. The mac
address list maintained in netxen_adapter needs to deleted when
driver is going down.

[PATCHv2 6/7] netxen: hold tx lock while sending firmware commands

[Dhananjay Phadke]

Some firmware commands like mac address addition/deletion are sent
on the transmit ring. So need to hold the tx lock before touching
tx producer/consumer indices.
