[PATCH net-next 00/14] be2net: patch set

[Sathya Perla]

Patches 1 to 6 address issues with return values of some ndo/ethtool
driver methods. In error scenarios, either an inappropriate error or
a +ve return value (where the stack expects a -ve value) was being returned.

Patch 7 updates description strings for certain UE bits.

Patch 8 cleans up (reduces) argument passing for a few routines in be_cmds.c.

Patch 9 removes some unused code (unused definitions.)

Patch 10 updates NULL check in the driver to a consistent "if (!foo)" style.

Patchs 11 to 13 fix a few minor issues with the earlier patch bec84e6
("create optimal number of queues on SR-IOV config"):
	- patch 11 fixes BEx_get_resources() code to use be_max_vfs() macro
	- patch 12 skips SR-IOV config code for BE2 that doesn't support SRIOV
	- patch 13 uses adapter->flags to track SRIOV enabled state

Patch 14 updates the driver version.

Please consider applying to the net-next tree. Thanks.

[PATCH net-next 01/14] be2net: use -ENETDOWN error status when interface is down

[Sathya Perla]

From: Kalesh AP <kalesh.purayil@emulex.com>

Updating VF's tx-rate and FW-download are not allowed when the interface is
down. In such cases return -ENETDOWN to the stack.

[PATCH net-next 05/14] be2net: fix return status of some ethtool methods

[Sathya Perla]

From: Kalesh AP <kalesh.purayil@emulex.com>

ethtool expects a -ve status value to be returned when a driver method
encounters an error. The driver was directly passing the
error status returned by FW (a positive value) to ethtool.
This patch fixes this by returning -EIO status in cases where FW returns
an error.

[PATCH net-next 08/14] be2net: reduce arguments passed to FW-cmd routines

[Sathya Perla]

From: Kalesh AP <kalesh.purayil@emulex.com>

A pointer to adapter struct is passed anyway to all of the FW-cmd routines
in be_cmds.c. For routines which query data from FW, the adapter pointer
is enough to return the queried fields.
There is no need to separately pass pointers to individual members of
the adapter structure. This patch fixes this for be_cmd_get_fw_ver()
and be_cmd_get_fw_cfg() routines.

[PATCH net-next 11/14] be2net: use be_max_vfs() macro to access max-vfs

[Sathya Perla]

From: Vasundhara Volam <vasundhara.volam@emulex.com>

max-vfs value must be accessed via the macro be_max_vfs(adapter).
The earlier patch "create optimal number of queues on SR-IOV config"
by mistake, did not use this macro. This patch fixes it.

[PATCH net-next 13/14] be2net: use adapter->flags to track SRIOV state

[Sathya Perla]

From: Vasundhara Volam <vasundhara.volam@emulex.com>

The driver so far used adapter->num_vfs value to check if SR-IOV is enabled
or not. But, the patch bec84e6("create optimal number of queues on SR-IOV
config") changed this logic. The adapter->num_vfs value is validated and set
much before SR-IOV is enabled. So, we now use an explicit flag to track
SR-IOV enabled state.
