When dropping into debug mode in a failed probe, make sure that
the AdminQ is left alive for possible hand debug of driver and

Move the mutex_init calls earlier in probe so that if init fails,

This patch enables bulk Tx clean for skbs. In order to enable it we need
to pass the napi_budget value as that is used to determine if we are truly
running in NAPI mode or if we are simply calling the routine from netpoll
with a budget of 0. In order to avoid adding too many more variables I
thought it best to pass the VSI directly in a fashion similar to what we do
on igb and ixgbe with the q_vector.

In the polling routines for i40e and i40evf we were using bitwise operators
to avoid the side effects of the logical operators, specifically the fact
that if the first case is true with "||" we skip the second case, or if it
is false with "&&" we skip the second case. This fixes an earlier patch
that converted the bitwise operators over to the logical operators and
instead replaces the entire thing with just an if statement since it should
be more readable what we are trying to do this way.

From what I can tell the practical limitation on the size of the Tx data
buffer is the fact that the Tx descriptor is limited to 14 bits. As such
we cannot use 16K as is typically used on the other Intel drivers. However
artificially limiting ourselves to 8K can be expensive as this means that
we will consume up to 10 descriptors (1 context, 1 for header, and 9 for
payload, non-8K aligned) in a single send.
I propose that we can reduce this by increasing the maximum data for a 4K
aligned block to 12K. We can reduce the descriptors used for a 32K aligned
block by 1 by increasing the size like this. In addition we still have the
4K - 1 of space that is still unused. We can use this as a bit of extra
padding when dealing with data that is not aligned to 4K.
By aligning the descriptors after the first to 4K we can improve the
efficiency of PCIe accesses as we can avoid using byte enables and can fetch
full TLP transactions after the first fetch of the buffer. This helps to
improve PCIe efficiency. Below is the results of testing before and after
with this patch:
Recv Send Send Utilization Service Demand
Socket Socket Message Elapsed Send Recv Send Recv
Size Size Size Time Throughput local remote local remote
bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB
Before:
87380 16384 16384 10.00 33682.24 20.27 -1.00 0.592 -1.00
After:
87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -1.00
So the net result of this patch is that we have a small gain in throughput
due to a reduction in overhead for putting together the frame.

Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

Attackers like to use SYNFLOOD targeting one 5-tuple, as they
hit a single RX queue (and cpu) on the victim.
If they use random sequence numbers in their SYN, we detect
they do not match the expected window and send back an ACK.
This patch adds a rate limitation, so that the effect of such
attacks is limited to ingress only.
We roughly double our ability to absorb such attacks.

TCP uses per cpu 'sockets' to send some packets :
- RST packets ( tcp_v4_send_reset()) )
- ACK packets for SYN_RECV and TIMEWAIT sockets
By setting SOCK_USE_WRITE_QUEUE flag, we tell sock_wfree()
to not call sk_write_space() since these internal sockets
do not care.
This gives a small performance improvement, merely by allowing
cpu to properly predict the sock_wfree() conditional branch,
and avoiding one atomic operation.

Goal: packets dropped by a listener are accounted for.
This adds tcp_listendrop() helper, and clears sk_drops in sk_clone_lock()
so that children do not inherit their parent drop count.
Note that we no longer increment LINUX_MIB_LISTENDROPS counter when

When a SYNFLOOD targets a non SO_REUSEPORT listener, multiple
cpus contend on sk->sk_refcnt and sk->sk_wmem_alloc changes.
By letting listeners use SOCK_RCU_FREE infrastructure,
we can relax TCP_LISTEN lookup rules and avoid touching sk_refcnt
Note that we still use SLAB_DESTROY_BY_RCU rules for other sockets,
only listeners are impacted by this change.
Peak performance under SYNFLOOD is increased by ~33% :
On my test machine, I could process 3.2 Mpps instead of 2.4 Mpps
Most consuming functions are now skb_set_owner_w() and sock_wfree()
contending on sk->sk_wmem_alloc when cooking SYNACK and freeing them.

Tom Herbert would like not touching UDP socket refcnt for encapsulated
traffic. For this to happen, we need to use normal RCU rules, with a grace
period before freeing a socket. UDP sockets are not short lived in the
high usage case, so the added cost of call_rcu() should not be a concern.
This actually removes a lot of complexity in UDP stack.
Multicast receives no longer need to hold a bucket spinlock.
Note that ip early demux still needs to take a reference on the socket.
Same remark for functions used by xt_socket and xt_PROXY netfilter modules,
but this might be changed later.
Performance for a single UDP socket receiving flood traffic from
many RX queues/cpus.
Simple udp_rx using simple recvfrom() loop :
438 kpps instead of 374 kpps : 17 % increase of the peak rate.

- keep early demux break in __udp4_lib_demux_lookup()

We want a generic way to insert an RCU grace period before socket
freeing for cases where RCU_SLAB_DESTROY_BY_RCU is adding too
much overhead.
SLAB_DESTROY_BY_RCU strict rules force us to take a reference
on the socket sk_refcnt, and it is a performance problem for UDP
encapsulation, or TCP synflood behavior, as many CPUs might
attempt the atomic operations on a shared sk_refcnt
UDP sockets and TCP listeners can set SOCK_RCU_FREE so that their
lookup can use traditional RCU rules, without refcount changes.
They can set the flag only once hashed and visible by other cpus.

It is possible on some HW that a system reset could occur when we are
holding the SWFW semaphore lock. So next time the driver was loaded we
would see it incorrectly as locked. This patch will recover from that state
by: Attempting to acquire the semaphore and then regardless of whether or
not it was acquire we immediately release it. This will force us into
a known good state.

This patch adds support for generic Tx checksums to the ixgbevf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

- One interrupt for emac
- Four interrupts for dma queue (best effort rx/tx, network control rx/tx)
This patch improve efficiency of the interrupt handler by adding the
