Subject: [PATCH] bridge: fix link notification skb size calculation to include
 vlan ranges

my previous patch skipped vlan range optimizations during skb size
calculations for simplicity.

This incremental patch considers vlan ranges during
skb size calculations. This leads to a bit of code duplication
in the fill and size calculation functions. But, I could not find a
prettier way to do this. will take any suggestions.

Previously, I had reused the existing br_get_link_af_size size calculation
function to calculate skb size for notifications. Reusing it this time
around creates some change in behaviour issues for the usual
.get_link_af_size callback.

This patch adds a new br_get_link_af_size_filtered() function to
base the size calculation on the incoming filter flag and include
vlan ranges.
