[dpdk-dev] [PATCH v3 2/2] enic: more specific out of resources error messages

[John Daley <johndale@cisco.com>]

If configuration fails due to lack of resources, be more specific
about which resources are lacking - work queues, read queues or
completion queues.

Fixes: fefed3d1e62c ("enic: new driver")
Signed-off-by: John Daley <johndale@cisco.com>

v3: Log messages fix in separate patch. Log errors
for all lacking resources, not just 1st encountered.
