Summary of changes: - postpone mtu size assignment during load to avoid race condition - refactor some of the debug prints - add request reset handler - refactor flush scheduler to increase efficiency and avoid racing - put correct vlan_tag for UD traffic with PFC - suspend QP before going to ERROR state to avoid CQP timout - fix arithmetic error on irdma_debug_bugf - allow debug flag to be settable during driver load - introduce meaningful default values for DCQCN algorithm - interrupt naming convention improvements - skip unsignaled completions in poll_cmpl Signed-off-by: Bartosz Sobczak bartosz.sobczak@intel.com Signed-off-by: Eric Joyner <erj@FreeBSD.org> Reviewed by: hselasky@ MFC after: 1 week Sponsored by: Intel Corporation Differential Revision: https://reviews.freebsd.org/D39173
