[SCSI] bnx2i: Adjust sq_size module parametr to power of 2 only if a non-zero value is specified
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
