Update Intel irdma driver to version 1.2.17-k Notable changes: - pf-reset handling improvements, including fixes in communication with if_ice(4) - avoid racing when handling various events - adding sw stats sysctls - hand over pe_criterr handling from ice(4) to irdma(4) - debug prints adjustments - fix crash after changes in irdma_add_mqh_ifa_cb Signed-off-by: Bartosz Sobczak <bartosz.sobczak@intel.com> Signed-off-by: Eric Joyner <erj@FreeBSD.org> Reviewed by: erj@ MFC after: 1 month Sponsored by: Intel Corporation Differential Revision: https://reviews.freebsd.org/D41425
