I would like to determine the banwidth the card is getting from

/proc/net/dev exports counters; you can monitor those -- I'm sure
there are perfomance program that do exactly this.
For an ethernet, it could be either 10Mbps or 100Mbps, is there
any way of knowing from inside the kernel how much is the
bandwidth the card is actually receiving from the network,
especially when it is capable of getting either 10Mbps or
100Mbps?
The kernel counts packets and bytes; you need to work out bandwidth
in userland from that.
