The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=58d84ef87094691bf1ad9608964ec85f120cd34a commit 58d84ef87094691bf1ad9608964ec85f120cd34a Author: Sumit Saxena <sumit.saxena@broadcom.com> AuthorDate: 2022-11-04 22:40:29 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2022-11-04 22:40:29 +0000 if_bnxt: Added support for mgmt interface for passthrough hwrms Added support for application management interface. There are two types of commands supported: 1. Firmware IOCTLs: These ioctls are meant for firmware consumption. Driver acts as a transport for these. 2. Driver only IOCTLs: These ioctls are meant for driver consumption. Driver will serve these ioctls without sending them down to firmware.
