[net-next 0/8] stmmac: update to Oct 2011 version (v4)

This patches update the driver adding the chained
descriptor mode and some new useful fixes.

I've reviewed some patches after the V1/2/3 and added new ones:

 stmmac: allow mtu bigger than 1500 in case of normal desc (V4)
   |-> removed the useless max_mtu init: Thx Eric's feedback

 stmmac: add CHAINED descriptor mode support (V4)
   |-> removed ifdef in the C and added small routines
	specialised for chained/ring modes. See comment
	within the patch itself. Thx David's feedback.

 stmmac: allow mmc usage only if feature actually available (V4)
   |-> added a check if interface is NULL

 stmmac: limit max_mtu in case of 4KiB and use __netdev_alloc_skb.
  |-> another enhancements proposed by Eric (built on top of the
      V3 patches sent today).

 stmmac: use predefined macros for HW cap register fields (V4)
 stmmac: allow mmc usage only if feature actually available (V4)

Let me know if all is ok.

Regards
Peppe
