wcn36xx: enable the beaconing in mesh mode
Enable the beaconing in wnc36xx by tweaking the tim offset and
force the use of AP-style beaconing. Otherwise, beaconing is not
working. The tim offset is set to 256. Otherwise, this will
overwrite mesh beacon submitted by mac80211.

SNAP/LLC header in the AARP packet is being stripped off while
preparing an EthernetII header.
Annex M, Table M.3 in 802.11 spec says that some header
(ex. AppleTalk AARP(2)) should pass through untouched.
This patch modifies the check to exclude/include EthernetII
header translation for special cases.
