Subject: cnic: Fix mmap regression.
X-Git-Tag: v3.6-rc1~125^2~339
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=ae0eef66088777cf252c6b91d3eb5ef2f30a67c5;p=~emulex%2Finfiniband.git

cnic: Fix mmap regression.

commit 1f85d58cdf15354a7120fc9ccc9bb9c45b53af88
    cnic: Remove uio mem[0].

introduced a regression as older versions of userspace app still rely
on this mmap.  Restore the mmap functionality and get the base address
from pci_resource_start() as the nedev->base_addr has been deprecated for
PCI devices.

Update version to 2.5.12.
