[ovs-discuss] "ofproto-dpif - select group with dp_hash selection method" test fails on armv7l

[Timothy M. Redaelli]

Hi,
"ofproto-dpif - select group with dp_hash selection method" test fails
on armv7l.

I saw the problem during build of openvswitch 2.7.0 Fedora package since
all other architectures builds fine [1].

I see, also, that Ubuntu is disabling (all) tests on armhf for the same
problem [2]

I also replied the issue on bananapi (git version 0b4f83e2d) using
archlinuxarm [3]

It seems the test expect to have recirc(0x3), but it has recirc(0x2).

I can't replicate the problem on any other architecture supported by
Fedora (x86_64, ppc64le, aarch64, ppc64, i686 and s390x).
