100GbE Intel Wired LAN Driver Updates 2019-11-04
This series contains updates to the ice driver only.
Anirudh refactors the code to reduce the kernel configuration flags and
introduces ice_base.c file.
Maciej does additional refactoring on the configuring of transmit
rings so that we are not configuring per each traffic class flow.
Added support for XDP in the ice driver. Provides additional
re-organizing of the code in preparation for adding build_skb() support
in the driver. Adjusted the computational padding logic for headroom
and tailroom to better support build_skb(), which also aligns with the
logic in other Intel LAN drivers. Added build_skb support and make use
of the XDP's data_meta.
Krzysztof refactors the driver to prepare for AF_XDP support in the
driver and then adds support for AF_XDP.
v2: Updated patch 3 of the series based on community feedback with the
following changes...
- return -EOPNOTSUPP instead of ENOTSUPP for too large MTU which makes
it impossible to attach XDP prog
- don't check for case when there's no XDP prog currently on interface
and ice_xdp() is called with NULL bpf_prog; this happens when user
does "ip link set eth0 xdp off" and no prog is present on VSI; no need
for that as it is handled by higher layer
- drop the extack message for unknown xdp->command
- use the smp_processor_id() for accessing the XDP Tx ring for XDP_TX
action
- don't leave the interface in downed state in case of any failure
during the XDP Tx resources handling
- undo rename of ice_build_ctob

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the ixgbe
driver still allowed TX packets to request HW timestamping. In this
situation, we see 'clearing Tx Timestamp hang' noise in the log.
Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

This patch is meant to address locality issues present in the ixgbe driver
when it is loaded on a system supporting multiple NUMA nodes and more CPUs
then the device can map in a 1:1 fashion. Instead of just arbitrarily
mapping itself to CPUs 0-62 it would make much more sense to map itself to
the local CPUs first, and then map itself to any remaining CPUs that might
be used.
The first effect of this is that queue 0 should always be allocated on the
local CPU/NUMA node. This is important as it is the default destination if
a packet doesn't match any existing flow director filter or RSS rule and as
such having it local should help to reduce QPI cross-talk in the event of
an unrecognized traffic type.
In addition this should increase the likelihood of the RSS queues being
allocated and used on CPUs local to the device while the ATR/Flow Director
queues would be able to route traffic directly to the CPU that is likely to
be processing it.

I've observed around 30% less CPU consumption with build_skb Rx path, in

Take into account the underlying architecture specific settings and
based on that calculate the possible padding that can be supplied.
Typically, for x86 and standard MTU size we will end up with 192 bytes
of headroom. This is the same behavior as our other drivers have and we
can dedicate it for XDP purposes.
Furthermore, introduce the Rx ring flag for indicating whether build_skb

Add an ethtool "legacy-rx" priv flag for toggling the Rx path. This
control knob will be mainly used for build_skb usage as well as buffer
size/MTU manipulation.
In preparation for adding build_skb support in a way that it takes
care of how we set the values of max_frame and rx_buf_len fields of
struct ice_vsi. Specifically, in this patch mentioned fields are set to
values that will allow us to provide headroom and tailroom in-place.
This can be mostly broken down onto following:
- for legacy-rx "on" ethtool control knob, old behaviour is kept;
- for standard 1500 MTU size configure the buffer of size 1536, as
network stack is expecting the NET_SKB_PAD to be provided and
NET_IP_ALIGN can have a non-zero value (these can be typically equal
to 32 and 2, respectively);
- for larger MTUs go with max_frame set to 9k and configure the 3k
buffer in case when PAGE_SIZE of underlying arch is less than 8k; 3k
buffer is implying the need for order 1 page, so that our page
recycling scheme can still be applied;
With that said, substitute the hardcoded ICE_RXBUF_2048 and PAGE_SIZE
values in DMA API that we're making use of with rx_ring->rx_buf_len and
ice_rx_pg_size(rx_ring). The latter is an introduced helper for
determining the page size based on its order (which was figured out via
ice_rx_pg_order). Last but not least, take care of truesize calculation.
In the followup patch the headroom/tailroom computation logic will be
introduced.
This change aligns the buffer and frame configuration with other Intel
drivers, most importantly with iavf.

Add zero copy AF_XDP support. This patch adds zero copy support for
Tx and Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c.
For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse
existing XDP Tx queues for this task, since XDP_REDIRECT guarantees
mutual exclusion between different NAPI contexts based on CPU ID. In
turn, a netdev can XDP_REDIRECT to another netdev with a different
NAPI context, since the operation is bound to a specific core and each
core has its own hardware ring.
For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is

two tests are done for every packet entering the bridge if it's learning,
but for the fast-path we already have them checked in br_handle_frame() and
is unnecessary to do it again. Thus push the checks to the unlikely cases
and drop them from br_fdb_update(), the new nbp_state_should_learn() helper
