Pull rdma qedr RoCE driver from Doug Ledford:
 "Early on in the merge window I mentioned I had a backlog of new
  drivers waiting to be reviewed and that, in addition to the hns-roce
  driver, I wanted to get possible a couple more reviewed. I ended up
  only having the time to complete one of the additional drivers.

  During Dave Miller's pull request this go around, there were a series
  of 9 patches to the QLogic qed net driver that add basic support for a
  paired RoCE driver. That support is currently not functional because
  it is missing the matching RoCE driver in the RDMA subsystem. I
  managed to finish that review. However, because it goes against part
  of Dave's net pull, and a part that was accepted a day or two after
  the merge window opened, to apply cleanly it has to be applied to
  either the tip of Dave's net branch, or as I did in this case, I just
  applied it to your master after you had taken Dave's pull request."

 "This merge window was the first where Huawei had to try and coordinate
  their patches between their net driver and their new roce driver
  (similar to mlx4 and mlx5).

  They didn't do horribly, but there were some issues (and we knew that
  because they simply didn't know what to do in the beginning). As a
  result, I had a set of patches that depended on some patches that
  normally would have come to you via Dave's tree. Those patches have
  been on netdev@ for a while, so I got Dave to give me his approval to
  send them to you. As such, the other 29 patches I had behind them are
  also now ready to go.

  This catches the hns and hns-roce drivers up to current, and for
  future patches we are working with them to get them up to speed on how
  to do joint driver development so that they don't have these sorts of
  cross tree dependency issues again. BTW, Dave gave me permission to
  add his Acked-by: to the patches against the net tree, but I've had
  this branch through 0day (but not linux-next since it was off by
  itself) and I didn't want to rebase the series just to add Dave's ack
  for the 8 patches in the net area.

  Updates to the hns drivers:

   - Small patch set for hns net driver that the roce patches depend on

   - Various fixes to the hns-roce driver

   - Add connection manager support to the hns-roce driver"

This is supposed to loop 1000 times and then give up.  The problem is
it's a post-op and after the loop we test if "loop" is zero when really
it would be -1.  Fix this by making it a pre-op.

The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.

If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.

If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.

Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.

This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,
e.g. phy_error().

Wiht the latest rework of the xen-netback driver, we get a warning
on ARM about the types passed into min():

drivers/net/xen-netback/rx.c: In function 'xenvif_rx_next_chunk':
include/linux/kernel.h:739:16: error: comparison of distinct pointer types lacks a cast [-Werror]

The reason is that XEN_PAGE_SIZE is not size_t here. There
is no actual bug, and we can easily avoid the warning using the
min_t() macro instead of min().
