H A Dif_mskreg.hdiff 193298 Tue Jun 02 03:07:46 MDT 2009 yongari Add Rx checksum offloading support for Yukon FE+ and Yukon Extreme.
These controllers use newer descriptor format and the new descriptor
format uses status LE to indicate the status of checksum. Rx
checksummed value used in previous controllers were very cryptic
and I failed to understand how to use them. In addition most
controllers in previous generations had Rx checksum offloading bug.

While I'm here introduce a MSK_FLAG_NORX_CSUM flag to bypass
checking Rx checksum offloading as Yukon FE+ A0 has status LE bug.
