Log message:
Revert iwm(4) to software WPA crypto because of apparent firmware issues.
For a small proportion of frames on 8265 we have observed firmware reporting
"not encrypted" even though in Wireshark these frames appear as regular
encrypted frames (rx_pkt_status=0xc0400007 type=0x8 subtype=0x80 m_len=1542).
This causes frame drops which do not occur with software crypto.
We might try again after a firmware upgrade. There seems to be no public
record of bug fixes made by Intel between firmware versions which degrades
our development process into pure trial-and-error. We need to waste our own
time to find out information which Intel should be providing to the public.
If anyone is aware of a source of such information, please let us know.
All this is of course very disappointing.
Problem reported by and debugged with help from solene@
