Description
The thirty-seventh byte of the hash_key. The bits are in the big
endian format
The thirty-eighth byte of the hash_key. The bits are in the big endian
format
The thirty-ninth byte of the hash_key. The bits are in the big endian
format
The fortieth byte of the hash_key. The bits are in the big endian
format
IP 6 E
V XTENSION
Description
This bit enables programmable extension header #2. If this bit
is clear, then the value programmed in bits [15:8] of this register
will be ignored. If this bit is set, then extension headers will be
checked for a type matching the value in bits [15:8]. This bit
should be set to 0 if IPv6 RX is disabled.
This bit enables programmable extension header #1. If this bit
is clear, then the value programmed in bits [7:0] of this register
will be ignored. If this bit is set, then extension headers will be
checked for a type matching the value in bits [7:0]. This bit
should be set to 0 if IPv6 RX is disabled.
Reserved bits
These bits contain the programmable extension header value
for programmable header #2.
These bits contain the programmable extension header value
for programmable header #1.
