Subject: Redesign struct hostapd_ip_addr to be of fixed size
X-Git-Tag: hostap_0_7_1~237
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6aa9e7a64ac4677b03dfafc48f3ef1ed23fe8dd5;p=thirdparty%2Fhostap.git

Redesign struct hostapd_ip_addr to be of fixed size

This structure is embedded in some other structures and as such, it
would be nicer if this would not change its length based on build
options.
