Now that the only places which modify flags are either (a) during initialization prior to creating a netdevice, or (b) while holding the rtnl lock, we no longer need the cmpxchg64 call in i40e_set_priv_flags.

When we suspend and resume, we need to clear and re-enable the interrupt scheme. This was previously not done while holding the RTNL lock, which could be problematic, because we are actually destroying and re-creating queues. Hold the RTNL lock for the entire sequence of preparing for reset, and when resuming. This additionally protects the flags related to interrupt scheme under RTNL lock so that their modification is properly threaded. This is part of a larger effort to remove the need for cmpxchg64 in i40e_set_priv_flags().

The iWarp client flags are all potentially changed when the RTNL lock is not held, so they should not be part of the pf->flags variable. Instead, move them into the state field so that we can use atomic bit operations.

The two Flow Directory auto disable flags are used at run time to mark when the flow director features needed to be disabled. Thus the flags could change even when the RTNL lock is not held. They also have some code constructions which really should be test_and_set or test_and_clear using atomic bit operations. Create new state fields to mark this, and stop including them in pf->flags.

This flag is modified during run time, possibly even when the RTNL lock is not held. Additionally it has a few places which should be using test_and_set or test_and_clear atomic bit operations.

When NetworkManager is enabled, there are chances that interface up is called even before probe completes.

As defined in hyperv_net.h, the NVSP_STAT_SUCCESS is one not zero. Some functions returns 0 when it actually means NVSP_STAT_SUCCESS. This patch fixes them. In netvsc_receive(), it puts the last RNDIS packet's receive status for all packets in a vmxferpage which may contain multiple RNDIS packets.

The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two.

This implements the XDP_TX action which is modeled on the ixgbe implementation. However instead of using CPU id to determine which XDP queue to use, this uses the received RX queue index, which is similar to i40e. Doing this eliminates the restriction that number of CPUs not exceed number of XDP queues that ixgbe has. Also, based on the number of queues available, the number of TX queues may be reduced when an XDP program is loaded in order to accommodate the XDP queues.
