Merge branch 'be2net-next'

Sathya Perla says:

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

Patch 1 fixes some minor issues with log messages in be2net.

Patch 2 replaces strcpy() calls with strlcpy() to avoid possible buffer
overflow.

Patch 3 improves the RX buffer posting scheme for jumbo frames.

Patch 4 replaces the use of v0 of SET_FLOW_CONTROL cmd with v1 to receive
a definitive completion status from FW.

Patch 5 adds support for ethtool "-m" ethtool option.

Patch 6 fixes port-type reporting via ethtool get_settings for QSFP/SFP+
interfaces.

Patch 7 fixes the usage of MODIFY_EQD FW cmd to target a max of 8 EQs on
Lancer chip.

Patch 8 enables PCIe error reporting even for VFs.

Pls consider applying this patch set to net-next. Thanks.
