The branch main has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=cbb3ec25236ba72f91cbdf23f8b78b9d1af0cedf commit cbb3ec25236ba72f91cbdf23f8b78b9d1af0cedf Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-05-23 23:03:09 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-08-21 01:34:03 +0000 mt76: update driver from upstream This is a set of updates of the mt76 driver based on wireless-testing (wt-2023-05-11) 711dca0ca3d77414f8f346e564e9c8640147f40d (after v6.4-rc1), This adds support for mt7996 as well. (wt-2023-06-09) 7bd20e011626ccc3ad53e57873452b1716fcfaaa (after v6.4-rc5), (wt-2023-07-24) 62e409149b62a285e89018e49b2e115757fb9022 (after v6.5-rc3), (wt-2023-08-06) 2a220a15be657a24868368892e3e2caba2115283 (after v6.5-rc4). The current version of LinuxKPI lacks support for "page pool" which needs enhancing and updating a decade or so old shortcut mapping struct page directly to struct vm_page.
