Subject: net/ena: remove support of legacy LLQ
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1d339597a17561fb3b285a076100673381bec9a0;p=dpdk.git

net/ena: remove support of legacy LLQ

The legacy LLQ should no longer be supported by the drivers, as this API
is deprecated. Because of that, it was removed from the driver.
