Subject: [PATCH net-next-2.6 2/2] qlcnic: Add support for configuring eswitch
and npars
From: Rajesh Borundia <rajesh.borundia@...gic.com>
Following changes have been made:
1. Obtain capabilities of a NIC partition,
2. Configure tx bandwidth of particular NIC partition.
3. Configure the eswitch for setting port mirroring, enable mac
learning, promiscuous mode.
