[PATCH 04/13] qla3xxx: Add ethtool functionality to report pause parameters

[Ron Mercer <ron.mercer@qlogic.com>]

From: Benjamin Li <benjamin.li@qlogic.com>

We have added the ability to query the receive and transmit PAUSE flow
control frames parameters, in addition to the auto-negotiated status
using ethtool.
