mt76: fix a check wrongly giving us random ether addresses all the time

2026-02-07T00:57:52+00:00

Do not cover the is_valid_ether_addr() check under CONFIG_OF.
Unclear if this is an initial porting or a merging error before the
driver hit the FreeBSD src tree.
The end result was that we always got a random link-layer address,
while the individual drivers may have setup phy->macaddr and this
function would only overwride if given in device tree.
Only if both, driver and and the OF backup, fail then go and use
the random link-layer address.

While here adjust printing the random link-layer address using
a FreeBSD format specifier and not the unsupported Linux one.

mt76: mt7925: add missing LINUXKPI_PARAM_PREFIX

2026-02-07T00:57:51+00:00

There is a module_param_named() in the file so we need to set
LINUXKPI_PARAM_PREFIX to get it a uniq sysctl name.  mt7921
has the exact same option.  Without their individual prefixes
the names would clash on systems with both chipsets and not
work for both.

mt76: sort out MODULE_DEPEND for PCI and USB

2026-02-07T00:57:51+00:00

It is not enough to depend on mt76_core which then depends on linuxkpi
and linuxkpi_wlan.  Given each mt76 driver is its own module, each
also needs to depend on these linuxkpi modules.
In addition the core module usb part also has to depend on linuxkpi_usb.

This in addition to the previously sorted PCI drivers, allows (or will
allow) the individual chipsets (drivers) to load on systems with USB,
if compiled in, as well.

mt76: update Mediatek's mt76 driver

2026-01-23T13:52:47+00:00

This version is based on
git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
24d479d26b25bce5faea3ddd9fa8f3a6c3129ea7 ( tag: v6.19-rc6 ).

Notable change: license got switched from ISC to BSD-3-Clause-Clear.
util.h is now imported from upstream given it is no longer GPL-only.
See the upstream repository 909675fd4344f73aad5f75f123bd271ada2ab9fb
and a96fed2825d8dfb068bf640419c619b5f2df4218.

For us the new version should also help with page pools and DMA32.

mt76: add LINUXKPI_PARAM_PREFIX for module_param*

2025-12-03T19:54:45+00:00

In order to not overwrite sysctl/tunables under compat.linuxkpi
we need to prefix the module_param* names with a per-driver/file
designator to make them (more) uniq.  Add the FreeBSD specific
LINUXKPI_PARAM_PREFIX defines for that where missing in mt76.

mt76: util.h: extend worker name

2025-12-03T19:54:44+00:00

In mt76_worker_setup() add the "name" argument to the description
for the worker thread.  That way we have a chance to keep them apart.

While here, rename a variable and shorten the the (c)/SPDX section
according to new style.

mt76: ieee80211_is_first_frag() operates on the seq_ctrl field not on fc.

2025-12-03T19:54:44+00:00

Pass the correct field to ieee80211_is_first_frag(); otherwise the results
may vary.
