Subject: crypto: nx - Remove unnecessary maxauthsize check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=56fcf73a29007aa7bec2e3fc5da2962f3f72d610;p=openwrt%2Fstaging%2Fblogic.git

crypto: nx - Remove unnecessary maxauthsize check

The crypto layer already checks maxauthsize when setauthsize is
called.  So there is no need to check it again within setauthsize.
