From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.
Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36
sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.
Example:
To add a rule that directs packets from VLAN 2001 to queue 5:
ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 5 loc 0

From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.
Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>
Since it uses the same NIC table as rx flow vlan filter therefore
rx-flow vlan filter accepts only vlans that present on the interface
in case of rx-vlan-filter is on.
