Description
iSCSI Disable
Disable the iSCSI filtering.
iSCSI Dword Count
This field indicates the Dword count of the iSCSI header, which is used
for packet split mechanism.
NFS Write Disable
Disable filtering of NFS write request headers.
NFS Read Disable
Disable filtering of NFS read reply headers.
NFS Version
00b = NFS version 2.
01b = NFS version 3.
10b = NFS version 4.
11b = Reserved for future use.
IPv6 Disable.
Disable IPv6 packet filtering.
IPv6 Xsum Disable
Disable XSUM on IPv6 packets.
ACK Accelerate Disable
When this bit is set, the 82583V does not accelerate interrupt on TCP
ACK packets.
ACK data Disable
1b = The 82583V recognizes ACK packets according to the ACK bit in
the TCP header + No –CP data
0b = The 82583V recognizes ACK packets according to the ACK bit
only.
This bit is relevant only if the ACKDIS bit is not set.
IP Fragment Split Disable
When this bit is set, the header of IP fragmented packets are not set.
Extended status Enable
When the EXSTEN bit is set or when the packet split receive
descriptor is used, the 82583V writes the extended status to the Rx
