The cited commit add initialization of ethtool steering during
representor rx initializations without cleaning it up in representor
rx cleanup, this may cause for stale ethtool flows to remain after
moving back from switchdev mode to legacy mode.

Fixed by calling ethtool steering cleanup during rep rx cleanup.

On failure to attach the netdev, fix the rollback by re-setting the
device's state back to MLX5E_STATE_DESTROYING.

Failing to attach doesn't stop statistics polling via .ndo_get_stats64.
In this case, although the device is not attached, it falsely continues
to query the firmware for counters. Setting the device's state back to
MLX5E_STATE_DESTROYING prevents the firmware counters query.

find_next_chained_ft(prio) returns the first flow table in the next
priority. If prio is a parent of a flow table then it returns the first
flow table in the next priority in the same namespace, else if prio
is parent of namespace, then it should return the first flow table
in the next namespace. Currently if the user requests to forward to
next namespace, the code calls to find_next_chained_ft with the prio
of the next namespace and not the prio of the namesapce itself.

This patch fixed 2 issues with the usage of skb_cow in LAPB drivers
"lapbether" and "hdlc_x25":

1) After skb_cow fails, kfree_skb should be called to drop a reference
to the skb. But in both drivers, kfree_skb is not called.

2) skb_cow should be called before skb_push so that is can ensure the
safety of skb_push. But in "lapbether", it is incorrectly called after
skb_push.

More details about these 2 issues:

1) The behavior of calling kfree_skb on failure is also the behavior of
netif_rx, which is called by this function with "return netif_rx(skb);".
So this function should follow this behavior, too.

2) In "lapbether", skb_cow is called after skb_push. This results in 2
logical issues:
   a) skb_push is not protected by skb_cow;
   b) An extra headroom of 1 byte is ensured after skb_push. This extra
      headroom has no use in this function. It also has no use in the
      upper-layer function that this function passes the skb to
      (x25_lapb_receive_frame in net/x25/x25_dev.c).
So logically skb_cow should instead be called before skb_push.

There's a potential race in xennet_remove(); this is what the driver is
doing upon unregistering a network device:

  1. state = read bus state
  2. if state is not "Closed":
  3.    request to set state to "Closing"
  4.    wait for state to be set to "Closing"
  5.    request to set state to "Closed"
  6.    wait for state to be set to "Closed"

If the state changes to "Closed" immediately after step 1 we are stuck
forever in step 4, because the state will never go back from "Closed" to
"Closing".

Make sure to check also for state == "Closed" in step 4 to prevent the
deadlock.

Also add a 5 sec timeout any time we wait for the bus state to change,
to avoid getting stuck forever in wait_event().
