[dpdk-stable] [PATCH v2 1/2] qede: reduce trace verbosity level

[Igor Russkikh]

On some hardware units it was found this trace is flooding the output,
making any dpdk interactive usage kind of problematic.

It is only informational, without any consequences handling, so reducing
it to verbose from explicit notice level.

[dpdk-stable] [PATCH v2 2/2] qede: make driver accept bigger rss tables

[Igor Russkikh]

We found some dpdk applications blindly pass fixed side rss hash tables,
and do not check driver/device capabilities.

Moreover, many other drivers do not do such a strong check as well.

So here we fix it, making qede accept any size rss_key. For larger key
tables we just crop it with notice trace message.

Could you rewrite the git commit by removing "We".

Waiting for Ack to merge this.
