Receive Address High (RAH). The upper 16 bits of the 48-bit Ethernet address n
(n=0…3).
Address Select (ASEL). Selects how the address is to be used. 00b means that it is
used to decode the destination MAC address.
VMDq output index (VIND). Defines the VMDq output index associated with a
receive packet that matches this MAC address (RAH and RAL).
Reserved. Reads as 0b. Ignored on write.
All Nodes Multicast Address valid (MAV). The all nodes multicast address
(33:33:00:00:00:01) is valid when this bit is set. Note that 0x33 is the first byte
on the wire.
Address valid (AV). When this bit is set the relevant address 3 is valid (compared
against the incoming packet).
Multiple Receive Queues Enable (MRxQueue). Enables support for multiple receive
queues and defines the mechanism that controls queue allocation. This field can
be modified only when receive to host is not enabled (RCTL.EN = 0).
00b = Multiple receive queues are disabled.
01b = Multiple receive queues as defined by Microsoft* RSS. The RSS field enable
bits define the header fields used by the hash function.
10b = VMDq enable, enables VMDq operation as defined in section receive.
queuing for virtual machine devices.
11b = Reserved.
Reserved.
RSS Field Enable. Each bit, when set, enables a specific field selection to be used
by the hash function. Several bits can be set at the same time.
Bit[16] = Enable TcpIPv4 hash function.
Bit[17] = Enable IPv4 hash function.
Bit[18] = Enable TcpIPv6 hash function.
Bit[19] = Enable IPv6Ex hash function.
Bit[20] = Enable IPv6 hash function.
Bit[21] = Reserved.
Reserved.
