Subject: ofproto: Make check_table_id generic
X-Git-Tag: sliver-openvswitch-2.1.90-1~10^2~77
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=554764d1aac75030c319fc8e2fa87811149421fa;p=sliver-openvswitch.git

ofproto: Make check_table_id generic

Update check_table_id() so that rather than returning a flow_mod specific
error it simply returns true of false. And update callers accordingly.

This is in preparation for using check_table_id() in conjunction
with table_mod.

Also update check_table_id to use OFPTT_ALL.
