New features - Add sysctl "link_active_on_if_down" (defaults to 1 to match previous behavior): set this to 0 to have the driver bring the physical link down when the interface is brought administratively down - Add sysctl "temp" to read chip temperature on E810 devices; this requires a 4.30 or newer NVM (see package sysutils/intel-nvmupdate-100g) Bug fixes and general changes - (linked to irdma) properly propagate PF reset request from irdma driver - (linked to irdma) properly notify irdma of an impending PF reset - (linked to irdma) move Protocol Engine error handling to irdma - Print log message when using a DDP that doesn't support the "TX balancing" mode - Block LLDP agent configuration when DSCP QoS mode is enabled - Fix kernel panic when updating NVM when adapter is in the "TX balancing" mode - Remove ice_sbq_cmd.h since it's unused - Fix LLDP RX filter to still allow LLDP frames to be received by SW after a PF reset in SW LLDP mode - Add ice_if_needs_restart handler in order to fix a bad VLAN and link down interaction - Issue PF reset during unload - nvmupdate process fixes - Use pci_msix_table_bar() to get MSI-X bar index at runtime instead of hardcoding it Signed-off-by: Eric Joyner <erj@FreeBSD.org> Reviewed by: anzhu@netapp.com Sponsored by: Intel Corporation, NetApp Differential Revision: https://reviews.freebsd.org/D41655 (cherry picked from commit 9c30461dd25bac49045acbeac10e00b6cc13d2bc)
