Burstiness of a flow is determined by the depth of a bucket, When the upper rate of shaper is large, the current depth of a bucket is not enough.

Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new count in a field of MC_CMD_GET_CAPABILITIES_V4.

2017-12-20s390/qeth: robustify qeth_get_ip_version()Julian Wiedmann1-6/+8
Instead of assuming that skb->data points to the Ethernet header, use the right helper and struct to access the Ethertype field. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-12-20s390/qeth: align L2 and L3 set_rx_mode() implementationsJulian Wiedmann2-67/+43
Once all of qeth_l3_set_rx_mode()'s single-use helpers are folded back in, the two implementations actually look quite similar. So improve the readability by converting both set_rx_mode() routines to a common format. This also allows us to walk ip_mc_htable just once, instead of three times.

2017-12-20s390/qeth: use ether_addr_* helpersJulian Wiedmann6-37/+32
Be a little more self-documenting, and get rid of OSA_ADDR_LEN. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-12-20s390/qeth: consolidate qeth MAC address helpersJulian Wiedmann1-29/+18
For adding/removing a MAC address, use just one helper each that handles both unicast and multicast. Saves one level of indirection for multicast addresses, while improving the error reporting for unicast addresses. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-12-20s390/qeth: don't keep track of MAC address's cast typeJulian Wiedmann2-20/+8
Instead of tracking the uc/mc state in each MAC address object, just check the multicast bit in the address itself. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
