Subject: fix -Wformat-truncation warnings
X-Git-Url: http://git.openwrt.org/project/luci.git;master?a=commitdiff_plain;h=ccaabb4ea4b11382bffd9fb05558c390c1eb70c4;p=project%2Fiwinfo.git

fix -Wformat-truncation warnings

Increase buffer sizes to get rid of e.g.:
iwinfo_nl80211.c:797:41: note: 'snprintf' output between 24 and 279 bytes into a destination of size 64
