Subject: Fix gratuitious Linux incompatibility (different name for bpf insn
X-Git-Tag: V2-BETA-1-PATCH-9~9
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4048b50ac73731545fb74bc6f3e3ef18b0a247da;p=thirdparty%2Fdhcp.git

Fix gratuitious Linux incompatibility (different name for bpf insn
structure so that it doesn't refer to the hated Berkeley - GMAFB).
Reindent ifdefs, which are now confusingly deeply nested.
