0x0 Multicast Block All. Each bit in this field corresponds to one of the
lower 32 multicast groups (e.g., bit 0 corresponds to multicast
group 0, bit 1 corresponds to multicast group 1, and so on).
When a bit is set in this field for an enabled multicast group, the
PCI-to-PCI bridge associated with this register is blocked from for-
warding multicast TLPs associated with that multicast group
received on that port. This is an ingress port function performed on
received TLPs.
The value of bits greater than NUMGROUP in the MCCTL register
is ignored.
0x0 Multicast Block All. Each bit in this field corresponds to one of the
upper 32 multicast groups (e.g., bit 0 corresponds to multicast
group 32, bit 1 corresponds to multicast group 33, and so on).
When a bit is set in this field for an enabled multicast group, the
PCI-to-PCI bridge associated with this register is blocked from for-
warding multicast TLPs associated with that multicast group
received on that port. This is an ingress port function performed on
received TLPs.
The value of bits greater than NUMGROUP in the MCCTL register
is ignored.
0x0 Multicast Block Untranslated. Each bit in this field corresponds
to one of the lower 32 multicast groups (e.g., bit 0 corresponds to
multicast group 0, bit 1 corresponds to multicast group 1, and so
on).
When a bit is set in this field for an enabled multicast group, the
function associated with this register is blocked from forwarding
untranslated multicast TLPs associated with that multicast group
received on that port. This is an ingress port function performed on
received TLPs.
The value of bits greater than NUMGROUP in the MCCTL register
is ignored.
