Subject: util: Add ECONNECTREFUSED to enum nvme_connect_err
X-Git-Tag: v1.3~11^2~2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4df1f0da9b7c4260f9b13159d0e5d469d410f2cc;p=users%2Fsagi%2Flibnvme.git

util: Add ECONNECTREFUSED to enum nvme_connect_err

The kernel might return ECONNECTREFUSED when opening of a socket fails.
Add this missing errno to enum nvme_connect_err.
