[PATCH 1/9 net-next-2.6] qlcnic: Make PCI info available in all modes

[PATCH 1/9 net-next-2.6] qlcnic: Make PCI info available in all modes

[anirban.chakraborty]

From: Sony Chacko <sony.chacko@qlogic.com>

Before this fix, PCI info was available only when multiple NIC functions
are present on the same port.

[PATCH 3/9 net-next-2.6] qlcnic: Cleanup patch

[anirban.chakraborty]

From: Anirban Chakraborty <anirban.chakraborty@qlogic.com>

 1. Changed adapter structure to move away from embedding hardware and
    receive context structs and use pointers to those objects
 2. Packed all the structs that interface with FW
 3. Removed unused code and structs

[PATCH 4/9 net-next-2.6] qlcnic: Code optimization patch

[anirban.chakraborty]

From: Anirban Chakraborty <anirban.chakraborty@qlogic.com>

Optimized code resulted in achieving lower CPU utilization on transmit path
and higher throughput for small packet sizes (64 bytes).

[PATCH 7/9 net-next-2.6] qlcnic: Use flt method to determine flash fw region

[anirban.chakraborty]

From: Sritej Velaga <sritej.velaga@qlogic.com>

Use flash layout table to get flash fw starting address and its size.
If that fails, use legacy method.
