That's just a side effect of wifi and how net80211 tools were built.

The 54MB is the non-11n rate announce. Now, for greenfield 11n, I
think it'll show something faster, but for normal 802.11 deployments
that support 11abg as well as 11n, 11ac, etc - 54M is how fast the
11abg side of things can run.

If you read the manpage and look at the flags, you'll see "11n" is a
flag (H) in the flags section.

In bsdconfig? That's not cool. Yeah, please file a bug.

I'm going to eventually push some logging changes to stop it showing
up on the kernel console. So just stay tuned.

I think that's just a shortcoming from ifconfig, but wpa_supplicant
should support unicode? Hm. I'm not sure, I've never used unicode AP
characters here!
