The branch stable/15 has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=37513bf193d9ab0fd768621256c0d0b3bcb1ba14 commit 37513bf193d9ab0fd768621256c0d0b3bcb1ba14 Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-07-25 23:56:29 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-08-02 04:21:17 +0000 igc: fix RX accounting for multi-descriptor packets The receive path adds the running packet length to rx_bytes for every descriptor. A packet spanning descriptors of length l1, l2, and l3 is therefore counted as 3*l1 + 2*l2 + l3. Add each descriptor length once. Single-descriptor accounting remains unchanged.
