Thank you ddziuk!

Maybe I am not understanding what is returned from my netstat / entstat output.

Here is what I get from netstat -v (it is the same identical output for entstat.

Would you please point out the link speed of this system.

Thank you so much!

TXP(4)							   BSD Kernel Interfaces Manual 						    TXP(4)

NAME
txp -- 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device txp Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_txp_load="YES" DESCRIPTION
The txp interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the 3Com Typhoon/Sidewinder chipset. Basic Ethernet functions are provided as well as support for vlan(4) tag removal and insertion assistance, receive ip(4), tcp(4), and udp(4) checksum offloading, and transmit ip(4) checksum offloading. There is currently no support for transmit tcp(4) or udp(4) checksum offload- ing, tcp(4) segmentation, nor ipsec(4) acceleration. When a txp interface is brought up, by default, it will attempt to auto-negotiate the link speed and duplex mode. The speeds, in order of attempt, are: 100Mb/s Full Duplex, 100Mb/s Half Duplex, 10 Mb/s Full Duplex, and 10 Mb/s Half Duplex. The txp supports several media types, which are selected via the ifconfig(8) command. The supported media types are: media autoselect Attempt to autoselect the media type (default) media 100baseTX mediaopt full-duplex Use 100baseTX, full duplex media 100baseTX [mediaopt half-duplex] Use 100baseTX, half duplex media 10baseT mediaopt full-duplex Use 10baseT, full duplex media 10baseT [mediaopt half-duplex] Use 10baseT, half duplex HARDWARE
The txp driver supports the following cards: o 3Com 3CR990-TX-95 o 3Com 3CR990-TX-97 o 3Com 3cR990B-TXM o 3Com 3CR990SVR95 o 3Com 3CR990SVR97 o 3Com 3cR990B-SRV SEE ALSO
altq(4), arp(4), inet(4), intro(4), ip(4), miibus(4), tcp(4), udp(4), vlan(4), ifconfig(8) HISTORY
The txp driver first appeared in OpenBSD 2.9. BSD
January 26, 2012 BSD
