Hi,

FYI, your patch has been queued to LTS release 16.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/17. So please
shout if anyone has objections.

Thanks.

Kind regards,

Subject: [PATCH] net/qede/base: fix macros to check chip revision/metal

[ upstream commit 3b212853e478e45490668ea054ec351da1fbda43 ]

Fix the ECORE_IS_[AB]0() macros to check both the chip revision and the
chip metal. Realign defines in the struct ecore_dev.

Fixes: ec94dbc57362 ("qede: add base driver")
