Subject: [patch 01/14] 8390: add common net_device ops

From: Stephen Hemminger <[email-masked]>
Date: Tue, 25 Nov 2008 17:14:20 -0800

Fix the defactoring of ei_XXX functions in 8390 and 8390p.
Remove the tx_timeout hack since no driver including the 3c503
overrides tx_timeout at this time, looks like a legacy thing.

Also, since several drivers all have same hooks, provide common
netdev_ops.
