Separate IPv4 and IPv6 ptype bit mask table into 2 tables:
with or without L4 protocols.
When a flow filter without any l4 type is specified, the
ICE_FLOW_SEG_HDR_IPV_OTHER flag can be used to describe if user
want to create a IP rule target for all IP packet or just IP
packet without l4 header.

To apply different input set for GTP-U packet with or without extend
header as well as GTP-U uplink and downlink, we need to add TCAM mask
matching capability. This allows comprehending different PTYPE
attributes by examining flags from the parser. Using this method,
different profiles can be used by examining flag values from the parser.

A subsequent addition of an IP4 or IP6 rule after other rules would
overwrite any existing TCAM entries of related L4 protocols(ex: tcp4 or
udp6). This was due to the mask including too many TCAM entries. Add new
packet type masks with bits properly excluded so rules are not overwritten.

Flex-bytes allows for packet matching based on an offset and value. This
is supported via the ethtool user-def option. It is specified by providing
an offset followed by a 2 byte match value. Offset is measured from the
start of the MAC address.
The following restrictions apply to flex-bytes. The specified offset must
be an even number and be smaller than 0x1fe.
Example usage:
ethtool -N eth0 flow-type tcp4 src-ip 192.168.0.55 dst-ip 172.16.0.55 \
src-port 12 dst-port 13 user-def 0x10ffff action 32

Flow Director allows for redirection based on ntuple rules. Rules are
programmed using the ethtool set-ntuple interface. Supported actions are
redirect to queue and drop.
Setup the initial framework to process Flow Director filters. Create and
allocate resources to manage and program filters to the hardware. Filters
are processed via a sideband interface; a control VSI is created to manage
communication and process requests through the sideband. Upon allocation of
resources, update the hardware tables to accept perfect filters.
