Author: np Date: Wed Jan 4 06:54:05 2017 New Revision: 311260 URL: https://svnweb.freebsd.org/changeset/base/311260 Log: MFC r309666, r310033, r310049, r310100, r310152, and r310807. r309666: cxgbe(4): unsigned short isn't large enough to store link speed (which is in Mbps) for 100Gbps links. r310033: cxgbe(4): Retire t4_bus_space_read_8 and t4_bus_space_write_8. r310049: cxgbe(4): Fix the tid range shown for T6 cards in misc.tids. r310100: cxgbe(4): Deal with compressed error vectors. r310152: cxgbe(4): Fix typo in an unused macro. r310807: cxgbe(4): Updates to link configuration. - Update struct link_settings and associated shared code. - Add tunables to control FEC and autonegotiation. All ports inherit these values as their initial settings. hw.cxgbe.fec hw.cxgbe.autoneg - Add per-port sysctls to control FEC and autonegotiation.
