Subject: ixgbe: convert to use of PMD_REGISTER_DRIVER and fix linking
X-Git-Tag: spdx-start~10808
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7b9d82208b5ed4b09cb686a5a6b7643827f1d9ad;p=dpdk.git

ixgbe: convert to use of PMD_REGISTER_DRIVER and fix linking

Convert the ixgbe pmd driver to use the PMD_REGISTER_DRIVER macro.
This means that the test applications now have no reference to the ixgbe library
when building DSO's and must specify its use on the command line with the -d
option.  Static linking will still initalize the driver automatically.
