NAME
       nvmf_tcp	-- TCP transport for NVM Express over Fabrics

SYNOPSIS
       To  compile the module into the kernel, place the following line	in the
       kernel configuration file:

	     device nvmf_tcp

       Alternatively, to load the module at boot  time,	 place	the  following
       line in loader.conf(5):

	     nvmf_tcp_load="YES"

DESCRIPTION
       The  nvmf_tcp  module  implements the software TCP/IP transport for NVM
       Express over Fabrics.  It can be	used by	either	the  in-kernel	NVMeoF
       host driver or controller.

SYSCTL VARIABLES
       The  following  variables are available as both sysctl(8) variables and
       loader(8) tunables:

       kern.nvmf.tcp.max_transmit_data
	       The maximum data	payload	size of	C2H_DATA and H2C_DATA PDUs.  A
	       remote controller may enforce a lower  limit  on	 the  size  of
	       H2C_DATA	 PDUs  via the MAXH2CDATA parameter.  The default size
	       is 256 kilobytes.
