[PATCH net-next 2/5] bnx2: Restrict WoL support.

[Michael Chan]

On some quad-port cards that cannot support WoL on all ports due
to excessive power consumption, the driver needs to restrict WoL
on some ports by checking VAUX_PRESET bit.

[PATCH net-next 3/5] bnx2: Set rx buffer water marks based on MTU.

[Michael Chan]

The default rx buffer water marks for XOFF/XON are for 1500 MTU.  At
larger MTUs, these water marks need to be adjusted for effective
flow control.

Thank you

Eric, I've seen (and used) this idiom enough times that I think
it deserves a generic construct somewhere instead of replicating
this sequence over and over again.

Don't you agree? :-)
