Subject: net/ena/base: remove extra properties strings
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c06c51d16c0df62bb0f92a49241a526c46a097d0;p=dpdk.git

net/ena/base: remove extra properties strings

This buffer was never used by the ENA PMD. It could be used for
debugging, but it's presence is redundant now.
