Revision 23b4201dead410c4a5108a8e723240419ab75257 authored by Jian Shen on 12 March 2020, 07:11:04 UTC, committed by David S. Miller on 12 March 2020, 18:38:26 UTC
Currently, if VF is loaded on the host side, the host doesn't clear the VF's VLAN table entries when VF removing. In this case, when doing reset and disabling sriov at the same time the VLAN device over VF will be removed, but the VLAN table entries in hardware are remained. This patch fixes it by asking PF to clear the VLAN table entries for VF when VF is removing. It also clears the VLAN table full bit after VF VLAN table entries being cleared. Fixes: c6075b193462 ("net: hns3: Record VF vlan tables") Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

Usage:
$0 [-o <file>] [-l <dep_list>] [-u <uid>] [-g <gid>] {-d | <cpio_source>} ...
-o <file> Create initramfs file named <file> by using gen_init_cpio
-l <dep_list> Create dependency list named <dep_list>
-u <uid> User ID to map to user ID 0 (root).
<uid> is only meaningful if <cpio_source> is a
directory. "squash" forces all files to uid 0.
-g <gid> Group ID to map to group ID 0 (root).
<gid> is only meaningful if <cpio_source> is a
directory. "squash" forces all files to gid 0.
<cpio_source> File list or directory for cpio archive.
If <cpio_source> is a .cpio file it will be used
as direct input to initramfs.
All options except -o and -l may be repeated and are interpreted
sequentially and immediately. -u and -g states are preserved across
<cpio_source> options so an explicit "-u 0 -g 0" is required
to reset the root/group mapping.
