Author: np Date: Thu Jan 21 12:18:29 2010 New Revision: 202745 URL: http://svn.freebsd.org/changeset/base/202745 Log: MFC r194917,r194918,r197043,r197791,r199239,r199240,r200003,r201907,r202671,r202678: r194917: About to add 10Gbase-T to known media types, this is just a whitespace cleanup before that commit. No functional impact. r194918: Add 10Gbase-T to known ethernet media types Some parts of r194521 (convert the port and adapter locks from sx_locks to regular mutexes). r197043: There is no need to log anything for a ctrlq stall or restart. These are normal events. r197791: cxgb(4) updates, including: - support for the new Gen-2, BT, and LP-CR cards. - T3 firmware 7.7.0 - shared "common code" updates. r199239: The 10GBASE-T card should use an IPG of 1. Also enable the check for low power startup on this card. r199240: Don't disable the XGMAC's tx on ifconfig down. It is unnecessary and can cause false backpressure in the chip. Fix a us/ms mixup while here. r200003: T3 firmware 7.8.0 for cxgb(4) r201907: Extra parantheses to keep certain compilers happy. r202671: Fix for a cxgb(4) panic. cxgb_ioctl can be called by the IP and IPv6 layers with non-sleepable locks held. Don't (potentially) sleep in those situations. r202678: Complain if freelist queue sizes are significantly less than desired.
