Re: collision in the network card

[Martin Visser <martinvisser99 () gmail com>]

Any LAN (and I mean Ethernet) network built in the last 10 years simply
should not have collisions on it. Simply ensure all ports are configured
with full-duplex and it is something you don't have to contemplate.

Any time today if I see collision counters on a switch or host interface
today, I consider it a misconfiguration. (Even when the actual media might
be half-duplex, for instance some forms of wireless networking, the physical
interface to the hosts will (should!!)  always be full-duplex capable)
