Hi,
I have a Dell R7515 server with 2 2-port Broadcom NetXtreme BCM5720 cards

We have several of these ports connected to 10Gb mirror ports on Cisco
switches, and want
to generate netflow statistics from the traffic. But when we bring the
interface up
with promisc mode the driver does not seem to receive any traffic with tcpdump
-n -i bnxt2.
When we move the cable from a port on the Broadcom card to a port on a Intel
card
tcpdump -n -i ix0 shows lots of traffic.
/etc/rc.conf:
ifconfig_bnxt2="promisc -tso4 -ts06 -lro"
ifconfig_ix0="promisc"
ifconfig bnxt2:
bnxt2: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC>
metric 0 mtu 1500
options=e506bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>

Any advice?
