pccard: Remove wi(4) driver

2021-01-08T03:41:06+00:00

Remove wi(4). pccard is going away, and wi only supports PC Card
devices, though it has a minor amount of glue to also support
PCI cards. However, removing the one without removing the other
is hard, so the whole driver is being removed.

Relnotes: Yes

wi: clean up empty lines in .c and .h files

Warn for the non pccard attachments

2020-08-31T23:31:16+00:00

These devices have non-pccard attachments. Warn for those as well. Both an and
wi don't do the modern cyrpto needed to use these cards on secure wifi networks.
an needs firmware from Cisco, which I don't think was ever produced. wi could
in theory do it with raw frames and on-host encryption, but nobody has written
that in the 15 years since WEP was cracked.

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

2020-02-26T14:26:36+00:00

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE.  All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

Widen EPOCH(9) usage in PCI WLAN drivers.

2020-01-30T10:28:01+00:00

Make sure all occurrences of ieee80211_input_xxx() in sys/dev are
covered by a network epoch section. Do not depend on the interrupt
handler nor any taskqueues being in a network epoch section.

This patch should unbreak the PCI WLAN drivers after r357004.

Fix ieee80211_radiotap(9) usage in wireless drivers:

2019-03-11T01:27:01+00:00

- Alignment issues:
 * Add missing __packed attributes + padding across all drivers; in
most places there was an assumption that padding will be always
minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) -
padding was just missing.
 * Add __aligned(8) attribute for all Rx radiotap headers since they can
contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so
just drop the attribute here. Refresh ieee80211_radiotap(9) man page
accordingly.

- Since net80211 automatically updates channel frequency / flags in
ieee80211_radiotap_chan_change() drop duplicate setup for these fields
in drivers.

Tested with Netgear WG111 v3 (urtw(4)), STA mode.

Remove the all rights reserved clause from my copyright, and make
other minor tweaks needed where that might have created ambiguity.
