Author: yongari Date: Tue May 29 04:44:51 2012 New Revision: 236218 URL: http://svn.freebsd.org/changeset/base/236218 Log: MFC r235821: Don't force max payload size to 128. Root complex and Endpoint will negotiate with each other on the TLP payload size so blindly forcing the size to 128 can cause a completion error which in turn will stop device.
