The branch stable/13 has been updated by osamaabb: URL: https://cgit.FreeBSD.org/src/commit/?id=d5141ea592eaf1f7fbc24420fb9a6b32fe4b9c7d commit d5141ea592eaf1f7fbc24420fb9a6b32fe4b9c7d Author: Osama Abboud <osamaabb@amazon.com> AuthorDate: 2024-08-07 06:24:21 +0000 Commit: Osama Abboud <osamaabb@FreeBSD.org> CommitDate: 2024-10-31 14:55:20 +0000 ena: Add support for device request reset message over AENQ This commit adds a handler for the new aenq message ENA_ADMIN_DEVICE_REQUEST_RESET, which in turn causes the driver to trigger reset of a new type: ENA_REGS_RESET_DEVICE_REQUEST. Also adds counting of such occurrences in a new statistic for it. Approved by: cperciva (mentor) Sponsored by: Amazon, Inc.
