Broadcom Wi-Fi in Pinebook Pro extremely crashy

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

I am running NetBSD-current on the Pinebook Pro and have found the
Broadcom Wi-Fi very prone to crashes.

A 9.99.64 kernel from about a week ago kept spamming the console with
"bwfm0: checksum error". A 9.99.65 kernel from today does less of
this, but occasionally, e.g. when downloading large files over scp,
the system will hang after

bwfm0: checksum error
bwfm0: header larger than mbuf
bwfm0: checksum error

This is not a panic, the system just becomes totally unresponsive, and
I have to long-press the power button.

Is this a known issue?
