nfp: RX and XDP buffer fixes
Two trivial fixes for code introduced with XDP support. First
one corrects the buffer size we populate a register with. The
register is designed to be used for scatter transfers which
the driver (and most FWs) don't support so it's not critical.
The other one for DMA direction is mostly cosmetic, DMA API
doesn't seem to care today about the precise direction in sync

netfilter: nf_tables: don't call nfnetlink_set_err() if nfnetlink_send() fails
The underlying nlmsg_multicast() already sets sk->sk_err for us to
notify socket overruns, so we should not do anything with this return
value. So we just call nfnetlink_set_err() if:
1) We fail to allocate the netlink message.
or
2) We don't have enough space in the netlink message to place attributes,
which means that we likely need to allocate a larger message.
Before this patch, the internal ESRCH netlink error code was propagated
to userspace, which is quite misleading. Netlink semantics mandate that
listeners just hit ENOBUFS if the socket buffer overruns.

ixgbe: Limit use of 2K buffers on architectures with 256B or larger cache lines
On architectures that have a cache line size larger than 64 Bytes we start
running into issues where the amount of headroom for the frame starts
shrinking.
The size of skb_shared_info on a system with a 64B L1 cache line size is
320. This increases to 384 with a 128B cache line, and 512 with a 256B
cache line.
In addition the NET_SKB_PAD value increases as well consistent with the
cache line size. As a result when we get to a 256B cache line as seen on
the s390 we end up 768 bytes used by padding and shared info leaving us
with only 1280 bytes to use for data storage. On architectures such as
this we should default to using 3K Rx buffers out of a 8K page instead of
trying to do 1.5K buffers out of a 4K page.
To take all of this into account I have added one small check so that we
compare the max_frame to the amount of actual data we can store. This was
already occurring for igb, but I had overlooked it for ixgbe as it doesn't
have strict limits for 82599 once we enable jumbo frames. By adding this
check we will automatically enable 3K Rx buffers as soon as the maximum
frame size we can handle drops below the standard Ethernet MTU.
I also went through and fixed one small typo that I found where I had left
an IGB in a variable name due to a copy/paste error.
