Subject: net: dev: reduce both ingress hook ifdefs
X-Git-Tag: v4.2-rc1~130^2~250
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=e7582bab5d28ea72e07cf2c74632eaf46a6c1a50;p=linux.git

net: dev: reduce both ingress hook ifdefs

Reduce ifdef pollution slightly, no functional change. We can simply
remove the extra alternative definition of handle_ing() and nf_ingress().
