Subject: rtlwifi: rtl8192ee: Fix firmware header endian issues
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8d882bcf82743f20b0546088f935a718b4ae6f60;p=openwrt%2Fstaging%2Fblogic.git

rtlwifi: rtl8192ee: Fix firmware header endian issues

This driver is converted to use the common firmware header struct.
Because the old header definition failed to indicate that the multi-byte
entries should be little endian, several problems were thus exposed.
These are fixed.
