* This issue was discovered during 10G iscsi testing
* Default value of 'sq_size' module parameter is '0' which means
driver should use predefined SQ queue size when setting up iscsi
connection.
* roundup_pow_of_two(0) results in '1' and forces driver to setup
connections with send queue size of '1' and results in lower
performance as well

Ok.
