As far I understand MTU 2290 is native to wireless/ath/freebsd driver.
Look at this
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng <hostap>
But when freebsd creates wlan0 it's lowered to 1500. I tried with another
ath WiFi card this way - worked fine with 2290 MTU in a bridge. BTW 2290 is
max value, but it seems than noone looked into wifi MTU under freebsd,
theoretically it could be about 7k to 9k - normal jumbo frame. 2290 is some
kinda way of baby jumbo frames - they're slightly bigger than 1.5k.
So next is the bridge. By default bridge uses the MTU of a first member, so
if it will be a stock ethernet i-face so it'll be again 1500.
If you're asking me why am I to use increased MTU - I see it reasonable.
