Subject: [PATCH 3.16 123/366] bnx2x: use the right constant

3.16.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Julia Lawall <Julia.Lawall@...6.fr>

commit dd612f18a49b63af8b3a5f572d999bdb197385bc upstream.

Nearby code that also tests port suggests that the P0 constant should be
used when port is zero.

The semantic match that finds this problem is as follows:
