[PATCH v2 2/4] powerpc/ps3: gelic_udbg: use struct vlan_hdr from <linux/if_vlan.h>

From: Luis Henriques
Date: Mon Feb 08 2016 - 17:28:26 EST


Instead of defining the local struct vlantag use the standard definition
of vlan_hdr from <linux/if_vlan.h>.

The fields in the <linux/if_vlan.h> definition have different names:
- vlan -> h_vlan_TCI
- subtype -> h_vlan_encapsulated_proto

While there, use also the ETH_P_IP macro instead of an hard-coded 0x0800
value.
