[SRU][J:linux-bluefield][PATCH v1 1/1] UBUNTU: SAUCE: mlxbf_gige: dont log RX errors by default

[David Thompson]

BugLink: https://bugs.launchpad.net/bugs/2138128

During certain reset flows, the BF3 kernel log shows instances of
this MAC receive error:
  mlxbf_gige MLNXBF17:00: rx_mac_error ....
This log shows that a packet was received with a MAC error,
and this packet was dropped. While everything is handled OK,
this event should not be placed into dmesg log by default.

The initial "enable" value of the mlxbf_gige msglvl infrastructure logic
includes the value for NETIF_MSG_RX_ERR. The fix is to change the initial
value, removing NETIF_MSG_RX_ERR, and preventing any logging based on this
type of RX error. Instead, the driver has a counter tracking this type of
RX error and its value can be displayed via "ethtool -S oob_net0"
