Fix: Get Channel Cipher suite to list algo
Implemented Get channel cipher suite command to list the supported algorithms. Previously this command supported only list by cipher suite. Unit test: Verified that algorithms are listed for both byte3 bit7 set / un-set ipmitool raw 0x6 0x54 0x1 0x0 0x80 ipmitool raw 0x6 0x54 0x1 0x0 0x00 both listed alogrithms as expected Change-Id: I7b0ac74293cce869f5bcaa3c5ec226e1d237ccdf Signed-off-by: Richard Marian Thomaiyar <richard.marian.thomaiyar@linux.intel.com>
