VLAN: Increase permitted number of tags in a packet
VLAN_MAX_NESTED_TAGS is a misnomer, it sets a maximum on the total
number of tags in a packet, nested or not. It's possible to surpass the
current value of 10 with legal packets, e.g. jumbo frames that carry
entire DVB Base Band Frames with GSE (or TS/MPE) that have fifteen
PDUs each with a IP/VLAN/ARP. Raise it to a somewhat higher but still
small finite limit.
