This base commit looks harmless enough, but since it's likely just a
commit in your tree, it isn't really a clear indicator of how you set
this tree up....

But once I pulled this, it became clear you guys based your tree on a
net-next starting point.  You need to make that clear in the beginning.
 And unless you can't avoid it, don't do it.  I don't like having to
pull in Dave's net-next before I pull your code because it means I
can't submit my pull request to Linus during the merge window as a
single pull request, I have to split it up to be the stuff that is
based on net-next and the stuff based on my own next area.

Without going into excruciating detail, this is what I got when I
pulled your branch:

 273 files changed, 8891 insertions(+), 6637 deletions(-)
 create mode 100644 drivers/net/ethernet/qlogic/qede/qede_filter.c
 create mode 100644 drivers/net/ethernet/qlogic/qede/qede_fp.c

Please don't do this unless you absolutely have to.
