Log message:
apply a fix by Steven Chamberlain <[email protected]>, via freebsd:
Fix an issue with 11g beacon frames which looks to be a limitation
on the largest multi-write size:
==
I looked further into the magic 88-byte threshold after which the bug
occurs. It turns out that figure included the 24-byte tx_desc, and up
to 64 bytes of beacon frame (header+data).
rum_write_multi doesn't seem happy with writing >64 bytes at a time to
the MAC register. If I break it up into separate calls (e.g. bytes
0-63, then bytes 64-65, written at the appropriate offset) I see the
proper beacon frames being transmitted now.
