Subject: net/ice: fix protocol extraction devargs parsing
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=83665e492f9daf13aad5647f378df29c3922dc2a;p=dpdk.git

net/ice: fix protocol extraction devargs parsing

If the default dev args 'proto_xtr' is not in the first position, it
will overwrite the parsed queue map value, so use an new variable to
save the default.

And enhance the error message printing to show the right information.

Fixes: 7e124ff12c85 ("net/ice: support protocol extraction per Rx queue")
