8.11.4 Immediate Interrupt Rx VLAN Priority - IMIRVP (0x5AC0; R/W)
8.11.5 SYN Packet Queue Filter - SYNQF (0x55FC; RW)
8.11.6 EType Queue Filter - ETQF (0x5CB0 + 4*n[n=0...7]; RW)
Field Bit(s) Initial Value Description
Vlan_Pri 2:0 000b
VLAN Priority.
This field includes the VLAN priority threshold. When Vlan_pri_en is set to 1b, then an
incoming packet with a VLAN tag with a priority field equal or higher to VlanPri triggers
an immediate interrupt, regardless of the EITR moderation.
Vlan_pri_en 3 0b
VLAN Priority Enable.
When set to 1b, an incoming packet with VLAN tag with a priority equal or higher to
Vlan_Pri triggers an immediate interrupt, regardless of the EITR moderation.
When set to 0b, the interrupt is moderated by EITR.
Reserved 31:4 0x0
Reserved.
Write 0x0, ignore on read.
Field Bit(s) Initial Value Description
Queue Enable 0 0b
When set, enables forwarding of Rx packets to the queue indicated in this
register.
Rx Queue 3:1 0x0 Identifies an Rx queue associated with SYN packets. Valid values are 0 to 3.
Reserved 31:4 0x0
Reserved.
Write 0x0, ignore on read.
Field Bit(s) Initial Value Description
EType 15:0 0x0
Identifies the protocol running on top of IEEE 802. Used to forward Rx packets
containing this EType to a specific Rx queue.
Rx Queue 18:16 0x0 Identifies the receive queue associated with this EType. Valid values are 0 to 3.
Reserved 19 0x0
Reserved.
Write 0x0, ignore on read.
EType Length 24:20 0x0
Ethertype Length. When enabled by Ethertype length enable this field defines the
length of the Ethertype specified by EType and the device continues parsing
incoming packets post this EType. The length includes the Ethertype itself as well
as the data portion that is followed for this Ethertype. The minimal Ethertype
length supported is 4 bytes.
EType Length
Enable
25 0x0
Ethertype Length Enable. When set indicates the Ethertype length defined in
EType Length is valid.
Filter enable 26 0b
When set, this filter is valid. Any of the actions controlled by the following fields
are gated by this field.
Reserved 28:27 0x0
Reserved.
Write 0x0, ignore on read.
