I do, for 2 reasons.  

One: We have a panel LED for link/no link/connected to PC state.  Often the
user can't see the jack or switch.  Gets the 2 basic connectivity questions
answered quickly.

Two: On loss of link we reset/abort the connection and delay to force the PC
to see no activity.  Our system is real time and we don't want link glitches
to cause pauses that don't close the connection but effect the program's
operation causing "bug reports".  We'd rather have a fatal disconnect error.

Subject: [lwip-users] Ethernet link state: needed ?

Hi folks,
I wrote a driver for the DM9000 Ethernet chip, and nowadays it is missing
the link state part. I feel reluctant to add it because I don't really see a
need for the stack/application to know the link state, since all the devices
I can imagine I'll be developing will be permanently attached to the
network, and not mobile devices like a laptop.

My question to the lwIP users: does anyone have the need to know the link
state ? Can you share why ?

Thank you, regards
