Author: kib Date: Mon Aug 20 12:07:10 2012 New Revision: 239414 URL: http://svn.freebsd.org/changeset/base/239414 Log: MFC r232197 (on behalf of phk): Also call the low-level driver if ->c_iflag & (IXON|IXOFF|IXANY) changes. Uftdi(4) examines (c_iflag & (IXON|IXOFF)) to control hw XON-XOFF support. This is obviously no good, if changes to those bits are not communicated down the stack.
