9cf1841c4a
Includes various feature improvements and bug fixes. Notable changes include: - Firmware logging support - Link management flow changes - New sysctl to report aggregated error counts - Health Status Event reporting from firmware (Use the new read-only tunables hw.ice.enable_health_events / dev.ice.#.enable_health_events to turn this off) Signed-off-by: Eric Joyner <erj@FreeBSD.org> Sponsored by: Intel Corporation
