Subject: Change formatting of u32 back to default
X-Git-Tag: v2.6.26~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=44dcfe820185;p=thirdparty%2Fiproute2.git

Change formatting of u32 back to default

Don't break scripts that depend on previous offset/value format.
Introduce a new -pretty flag for decoding, and (*gasp*) document
the formatting arguments.
