be2net: fix incorrect setting of cmd_privileges for VFs
Browse files Browse the repository at this point in the history
An earlier commit (f25b119 "Fix error messages while driver load for VFs")
incorrectly set the adapter->cmd_privileges value for VFs (in a
multi-channel config) to MAX_PRIVILEGES. This causes FW cmd failures
and avoidable error logs when certian cmds are issued by a VF.
Also, move the multi-channel hack to be_cmds.c inside
be_cmd_get_fn_privileges() routine.

Fixes: f25b119 "Fix error messages while driver load for VFs"
