IPv6 Neighbor Solicitation Message Filter
In IPv6, a Neighbor Solicitation Message packet (type 135) is used for address
resolution. A flexible filter can be used to check for a Neighborhood Solicitation
Message packet (type 135).
The fields checked for detection of a Neighbor Solicitation Message packet (type 135)
are type, code and addresses.
Accessing The 82577’s Wake Up Register Using MDIC
When software needs to configure the wake up state (either read or write to these
registers) the MDIO page should be set to 800 (for host accesses) until the page is not
changed to a different value wake up register access is enabled. Refer to
for more details.
After the page is set to the wake up page, the Address field is no longer translated as
reg_addr (register address) but as an instruction. If the given address is in [0..15]
range meaning PHY registers, the functionality remains unchanged.
There are two valid instructions:
