Subject: odp-util: Bump up maximum number of ODP actions.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ad8ee2c0f3b7d0e53aab749da97a9c78765d74fa;p=openvswitch

odp-util: Bump up maximum number of ODP actions.

The kernel supports more than a single page of actions now, so userspace
should be able to take advantage of this.

Upcoming commits will completely replace this data structure but this
commit makes the bug fix clear and is suitable for cherry-picking to
long-term support branches.
