|
|
* In addition it can be used to discard traffic that

|

* @mac_filter_entries: Number of entries in the MAC address filtering

* unicast and multicast entries. The primary MAC address
|

* @num_tcs: Number of traffic classes (TCs), reserved for the DPNI.
|

|
|
* BPs (DPNI_ SET_POOLS), policers. There are dedicated QM
|

* queues for traffic classes (including class queues on

|
* Tx). Value 0 defaults to one TC. Maximum supported value

* is 16. There are maximum 16 TCs for Tx and 8 TCs for Rx.
|
|
* When num_tcs>8 Tx will use this value but Rx will have

|
* only 8 traffic classes.
|
|
* @num_rx_tcs: if set to other value than zero represents number

|
|
* in num_tcs parameter.

* table is used to select the TC for ingress traffic. It
|
|
* is either an exact match or a TCAM table, depending on
|
|
* DPNI_OPT_ HAS_KEY_MASKING bit in OPTIONS field. This
