Merge branch 'qed-next'

Yuval Mintz says:

====================
qed*: driver updates

[Was previous termed 'eeprom access et al.', but seemed a bit
inappropriate given we've dropped the eeprom patch for now.
Still waiting for some inputs on that one, BTW]

This patch series contains some ethtool-related enhancements.
====================
