73725d9dfd nfp: allocate ring SW structs dynamically
To be able to switch rings more easily on config changes
allocate them dynamically, separately from nfp_net structure.

d79737c25e nfp: make *x_ring_init do all the init
nfp_net_[rt]x_ring_init functions used to be called from probe
path only and some of their functionality was spilled to the
call site.  In order to reuse them for ring reconfiguration
we need them to do all the init.

0afbfb183b nfp: break up nfp_net_{alloc|free}_rings
nfp_net_{alloc|free}_rings contained strange mix of allocations
and vector initialization.  Remove it, declare vector init as
a separate function and handle allocations explicitly.

0ba40af963 nfp: move link state interrupt request/free calls
We need to be able to disable the link state interrupt when
the device is brought down.  We used to just free the IRQ
at the beginning of .ndo_stop().  As we now move towards
more ordered .ndo_open()/.ndo_stop() paths LSC allocation
should be placed in the "allocate resource" section.

Since the IRQ can't be freed early in .ndo_stop(), it is
disabled instead.

ff1b68ab2d nfp: correct RX buffer length calculation
When calculating the RX buffer length we need to account
for up to 2 VLAN tags.  Rounding up to 1k is an relic of
a distant past and can be removed.  While at it also remove
trivial print statement.

a1cbaad75a asm-generic: remove old nonatomic-io wrapper files
The two header files got moved to include/linux, and most
users were already converted, this changes the remaining drivers
and removes the files.

4b402d71d3 nfp: call netif_carrier_off() during init
Netdevs default to carrier on, we should call netif_carrier_off()
during initialization since we handle carrier state changes in the
driver.

301c141d6a nfp: clear ring delayed kick counters
We need to clear delayed kick counters when we free rings otherwise
after ndo_close()/ndo_open() we could kick HW by more entries than
actually written to rings.

a188222b6e net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
    use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.
