[PATCH net-next 01/11] net: hns3: Disable vf vlan filter when vf vlan table is full
From: Salil Mehta
Date: Fri Jun 01 2018 - 12:57:05 EST
From: Yunsheng Lin <linyunsheng@xxxxxxxxxx>
This is only 128 entries for hardware's vf vlan table, when
the vf table is full, the firmware will disable the vf vlan
filter and return a resp_code of HCLGE_VF_VLAN_NO_ENTRY to
driver.
This patch checks the if resp_code from firmware is
HCLGE_VF_VLAN_NO_ENTRY, if yes, then print a warning and
return ok to the caller.
Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
