Subject: bnx2x: remove unused variable
X-Git-Tag: spdx-start~7426
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=52be0607bf5a76b871722885960314f2623ed125;p=dpdk.git

bnx2x: remove unused variable

The mbuf_alloc_size is leftover from BSD or some other code base.
It is set but never used in DPDK driver.  After that the related defines
can also be eliminated.
