find slot number and number of ports for each card

[saeedeh motlagh]

hello all

i want to have statistics about my hardware specially the type of card
that are installed on my system, the number of ports that each card
has and the slot number which cards are installed.  i can find the
slot number by tracing the output of dmesg but it's time consuming
job. more over, i don't know how to find the number of ports that each
card has.

please let me know if there is any command to give these information
to me directly.

thanks
