Thank you for the comments.

I updated the patch:
https://gist.githubusercontent.com/s-ymgch228/6597cfc4b6f79c6c62fcdf25003acb55/raw/8237c14badb390355613794f5e3dee92431a89d2/vlan_mtag.patch
https://gist.githubusercontent.com/s-ymgch228/6597cfc4b6f79c6c62fcdf25003acb55/raw/7169afbe597f3fb562cdc6afc4ef9caaa04d2542/vlan_mtag.patch.diff

Changes:
 - sys/mbuf.h
  - Add a comment like  /* 1: Used to be VLAN ID */
  - Add line breaks to M_COPYFLAGS
 - if_vlan.c
  - Fix branches
 - if_ether.h
  - Introduce vlan_has_tag and use it in drivers

the comments for the size of pkthdr on LP64 was not updated because
the result that I checked the size using the test code like
"printf("%lu\n", sizeof(struct pkthdr))" was 56 on amd64 after
applying the patch
