Merge branch 'be2net-next'

Sathya Perla says:

====================
be2net: patch set

v2 changes: add a new line after variable declaration in patch 12.

***
Patch 1 adds a few new log messages to help debugging in failure cases.

Patch 2 uses new macros for parsing RX/TX completions and TX wrbs to
help shorten the lines.

Patch 3 adds a description for the RX counter rx_input_fifo_overflow_drop.

Patch 4 adds TX completion error statistics reporting via ethtool.

Patch 5 adds a dma_mapping_error counter and its reporting via ethtool.

Patch 6 fixes up log messages in the Lancer FW download path.

Patch 7 replaces gotos with direct return statements.

Patch 8 cleans up be_change_mtu() code by using a new macro BE_MAX_MTU

Patch 9 makes be_cmd_get_regs() routine to return an integer status
similar to other FW cmd routines in be_cmds.c

Patch 10 gets rid of TX budget as enforcing a budget on TX completion
processing in NAPI is neither suggested nor it provides a performance benefit.

Patch 11 defines and uses a new macro for_all_tx_queues_on_eq() similar
to the RX processing code.

Patch 12 queries max_tx_qs from the FW for BE3 super-nic profiles.
For those profiles, the driver cannot assume a constant BE3_MAX_TX_QS value,
as the value may change for each function.

Please consider applying this patch set to the net-next tree. Thanks!
