The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=bbf0372feeb321a5bfeff7b1e79576ab01240441 commit bbf0372feeb321a5bfeff7b1e79576ab01240441 Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-07-25 23:56:29 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-07-26 01:00:02 +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.
