X-Git-Tag: firefly_0821_release~176^2~3001^2~35^2~1 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2a1ef4b5a72614c72fce0e21f44e996ee8f0ef23;p=firefly-linux-kernel-4.4.55.git qlcnic: Fix programming number of arguments in a command. o Initially we were programming maximum number of arguments. Instead we should program number of arguments required in a command. o Maximum number of arguments for 82xx adapter is four. Fix it for GET_ESWITCH_STATS command.
