bnx2: Clean up remaining iounmap

2012-09-27T23:18:50+00:00

commit c0357e975afdbbedab5c662d19bef865f02adc17 modified bnx2 to switch from
using ioremap/iounmap to pci_iomap/pci_iounmap.  They missed a spot in the error
path of bnx2_init_one though.  This patch just cleans that up.

bnx2x: remove false warning regarding interrupt number

2012-09-21T17:27:16+00:00

Since version 7.4 the FW configures in the pci config space the max
number of interrupts available to the physical function, instead of
the exact number to use.
This causes a false warning in driver when comparing the number of
configured interrupts to the number about to be used.

bnx2x: fix rx checksum validation for IPv6

2012-09-18T20:13:46+00:00

Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance
regression for IPv6. Rx checksum offload does not work. IPv6 packets
are passed to the stack with CHECKSUM_NONE.

The hardware obviously cannot perform IP checksum validation for IPv6,
because there is no checksum in the IPv6 header. This should not prevent
us from setting CHECKSUM_UNNECESSARY.

Tested on BCM57711.

bnx2x: Add missing afex code

2012-09-13T20:37:52+00:00

Commit a334872224a67b614dc888460377862621f3dac7 added afex support but lacked
several logical changes. This lack can cause afex to crash, and also
have a slight effect on other flows (i.e., driver always assumes the Tx ring
has less available buffers than what it actually has).

This patch adds the missing segments, fixing said issues.

bnx2x: fix registers dumped

2012-09-13T20:37:52+00:00

Under traffic, there are several registers that when read (e.g., via
'ethtool -d') may cause the chip to stall.
This patch corrects the registers read in such flows.

bnx2x: correct advertisement of pause capabilities

2012-09-13T20:37:52+00:00

This patch propagates users' requested flow-control into the link layer,
which will later be used to advertise this flow-control for auto-negotiation
(until now these values were ignored).

bnx2x: display the correct duplex value

2012-09-13T20:37:52+00:00

Prior to this fix, the driver reported the chip's active duplex state
is always 'full', even if using half-duplex mode.

bnx2x: prevent timeouts when using PFC

2012-09-13T20:37:52+00:00

Prevent updating the xmac PFC configuration when using a link speed
slower than 10G -the umac block is responsible for 1G or slower connections,
therefore it is possible the xmac block is reset when connection is slower.

bnx2x: fix stats copying logic

2012-09-13T20:37:51+00:00

FW needs the driver statistics for management. Current logic is broken
in that the function that gathers the port statistics does not copy
its own statistics to a place where the FW can use it.
This patch causes every function that can pass statistics to the FW to
do so.

bnx2x: Avoid sending multiple statistics queries

2012-09-13T20:37:51+00:00

During traffic when DCB is enabled, it is possible for multiple instances
of statistics queries to be sent to the chip - this may cause the FW to assert.

This patch prevents the sending of an additional instance of statistics query
while the previous query hasn't completed.
