IBM Processor for Network Resources
12.33: RXAAL Dropped Count Register
This register maintains a count of packets that are dropped due to a lack of resource. For example, if no
POOLS buffer (real or virtual mode) is available, the packet is dropped and this counter is incremented. This
count is useful when the chip is configured to only surface good packets.
When this counter overflows, a counter overflow event is generated to RXQUE.

12.34: RXAAL Maximum SDU Length Register
Specifies the maximum SDU size for a packet. This register contains the maximum SDU size for a packet.
This size includes only the protocol data length of the packet. For example, this length would be compared
with the AAL5 length field in the AAL5 trailer. When a packet is completely received, this register is used to
make sure it does not exceed the MSDU specified.
