Commit Message

Guoyang Zhou July 16, 2021, 9:54 a.m. UTC 
  The configuration of mtu is inconsistent in the driver and
firmware when the port is stopped, started and reconfigured.
Before, HINIC_MAX_JUMBO_FRAME_SIZE include vlan tag, but when
frame and pktlen are converted to each other do not include
vlan tag. And port_mtu_set function will use HINIC_MAX_JUMBO_FRAME_SIZE
to calculate eth_overhead, so mtu will be inconsistent in the driver and
firmware.

Fixes: e542ab51ab27 ("net/hinic: fix jumbo frame flag condition for MTU set")
