      mlxsw: Remove debugfs interface · 9a32562b
      由 Ido Schimmel 提交于 
      We don't use it during development and we can't extend it either, so
remove it.

      i40e: make use of hlist_for_each_entry_continue · 584a8870
      由 Jacob Keller 提交于 
      Replace a complex if->continue->else->break construction in
i40e_next_filter. We can simply use hlist_for_each_entry_continue
instead. This drops a lot of confusing code. The resulting code is much
easier to understand the intention, and follows the more normal pattern
for using hlist loops. We could have also used a break with a "return
next" at the end of the function, instead of return NULL, but the
current implementation is explicitly clear that when you reach the end
of the loop you get a NULL value. The alternative construction is less
clear since the reader would have to know that next is NULL at the end
of the loop.

      i40e: add support for SCTPv4 FDir filters · f223c875
      由 Jacob Keller 提交于 
      Enable FDir filters for SCTPv4 packets using the ethtool ntuple
interface to enable filters. The ethtool API does not allow masking on
the verification tag.

      i40e: implement support for flexible word payload · 0e588de1
      由 Jacob Keller 提交于 
      Add support for flexible payloads passed via ethtool user-def field.
This support is somewhat limited due to hardware design. The input set
can only be programmed once per filter type, and the flexible offset is
part of this filter input set. This means that the user cannot program
both a regular and a flexible filter at the same time for a given flow
type. Additionally, the user may not program two flexible filters of the
same flow type with different offsets, although they are allowed to
configure different values at that offset location.

We support a single flexible word (2byte) value per protocol type, and
we handle the FLX_PIT register using a list of flexible entries so that
each flow type may be configured separately.

Due to hardware implementation, the flexible data is offset from the
start of the packet payload, and thus may not be in part of the header
data. For this reason, the offset provided by the user defined data is
interpreted as a byte offset from the start of the matching payload.
Previous implementations have tried to represent the offset as from the
start of the frame, but this is not feasible because header sizes may
change due to options.

      i40e: add parsing of flexible filter fields from userdef · e793095e
      由 Jacob Keller 提交于 
      Add code to parse the user-def field into a data structure format. This
code is intended to allow future extensions of the user-def field by
keeping all code that actually reads and writes the field into a single
location. This ensures that we do not litter the driver with references
to the user-def field and minimizes the amount of bitwise operations we
need to do on the data.

Add code which parses the lower 32bits into a flexible word and its
offset. This will be used in a future patch to enable flexible filters
which can match on some arbitrary data in the packet payload. For now,
we just return -EOPNOTSUPP when this is used.

Add code to fill in the user-def field when reporting the filter back,
even though we don't actually implement any user-def fields yet.

Additionally, ensure that we mask the extended FLOW_EXT bit from the
flow_type now that we will be accepting filters which have the FLOW_EXT
bit set (and thus make use of the user-def field).

      i40e: partition the ring_cookie to get VF index · 43b15697
      由 Jacob Keller 提交于 
      Do not use the user-def field for determining the VF target. Instead,
similar to ixgbe, partition the ring_cookie value into 8bits of VF
index, along with 32bits of queue number. This is better than using the
user-def field, because it leaves the field open for extension in
a future patch which will enable flexible data. Also, this matches with
convention used by ixgbe and other drivers.
