N! packets dropped by kernel

Hi.  I have a situation which may or may not be a problem.  Here's my ip
configuration:

nge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.1.24 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::204:5aff:fe59:64f9%nge0 prefixlen 64 scopeid 0x2
        ether 00:04:5a:59:64:f9
        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active
nge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.1.25 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::204:5aff:fe59:5497%nge1 prefixlen 64 scopeid 0x3
        ether 00:04:5a:59:54:97
        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active

I've been monitoring net traffic with tcpdump.  Most traffic is SMB and
NMB.  Tcpdump reports a very high dropped:received packet ratio.  For
example, a few second of capture during peak traffic returns:

34964 packets received by filter
34085 packets dropped by kernel

Should I be concerned?  I'll include full tcpdumps on both interfaces if
necessary.  Thanks for your time.
