Author: phk Date: Sun Feb 26 20:56:49 2012 New Revision: 232197 URL: http://svn.freebsd.org/changeset/base/232197 Log: 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.
