Programming Interface — Ethernet Controller I210

8.18.43 BMC2OS Packets Received by Host - B2OGPRC (0x4158;
RC)
This register counts the total number of packets originating from the MC that reached the host.
If a packet is replicated, this counter counts each replication of the packet.
The counter clears when read by the software device driver. The counter also clears by a PCIe reset and
software reset. When reaching the maximum, the value counter does not wrap-around.
8.18.44 OS2BMC Packets Received by MC - O2BGPTC (0x8FE4; RC)
This register counts the total number of packets originating from the host that reached the NC-SI
interface.
The counter clears when read by the software device driver. The counter also clears by a PCIe reset and
software reset. When reaching maximum value, the counter does not wrap-around.
8.18.45 OS2BMC Packets Transmitted by Host - O2BSPC (0x415C; RC)
This register counts the total number of packets originating from the function that were sent to the
manageability path. This includes packets received by the MC and packets dropped in the I210 due to
congestion conditions.
Packets are dropped due to security reasons. For example, anti spoofing is not counted by this counter.
The counter is cleared when read by software device driver. The counter is also cleared by PCIe reset
and software reset. When reaching a maximum value, the counter does not wrap-around.
8.18.46 Total Octets Received - TORL (0x40C0; RC)
These registers make up a logical 64-bit register that counts the total number of octets received. This
register must be accessed using two independent 32-bit accesses; TORL must be read before TORH.
This register sticks at 0xFFFF_FFFF_FFFF_FFFF when the maximum value is reached.
All packets received have their octets summed into this register, regardless of their length, whether
they are erred, or whether they are flow control packets. This register includes bytes received in a
packet from the <Destination Address> field through the <CRC> field, inclusive. This register only
increments if receives are enabled (RCTL.RXEN is set).
Note: Broadcast rejected packets are counted in this counter (as opposed to all other rejected
packets that are not counted).
