svn commit: r291228 - projects/cxl_iscsi/sys/dev/iscsi

[Navdeep Parhar]

Author: np
Date: Tue Nov 24 01:12:17 2015
New Revision: 291228
URL: https://svnweb.freebsd.org/changeset/base/291228

Log:
  Do not generate PDUs with payload greater than max_data_segment_length.
  
  It is perhaps preferable to have a separate limit for send instead of
  reusing the receive limit.  I'll discuss with trasz@ and mav@ before
  pulling this into head.
