See if you have /proc/net/nicinfo/*.info on your system... will simplify this entire process....

EDIT. Had some more time to work on this. You may find the following useful:

Code:

#!/bin/bash

AWK="/usr/bin/awk"
CURL="/usr/bin/curl"
CUT="/usr/bin/cut"
ECHO="/bin/echo"
GREP="/bin/grep"
IFCONFIG="/sbin/ifconfig"
SED="/usr/bin/sed"
TR="/usr/bin/tr"

URL="http://www.coffer.com/mac_find/?string="

function get_interfaces {
  INTERFACES=$( ${IFCONFIG} -a | ${GREP} "^eth" | ${AWK} '{print $1}' )
}

function get_vendors {
  for INTERFACE in ${INTERFACES}; do
     MAC=$( ${IFCONFIG} ${INTERFACE} | ${GREP} "HWaddr" | ${AWK} '{print $NF}' )
     VENDOR=$( ${ECHO} "${MAC}" | ${CUT} -d":" -f1-3 )
     HTTPVENDOR=$( ${ECHO} "${VENDOR}" | ${SED} 's/:/%3A/g' )
     LOOKUP=$( ${CURL} "${URL}${HTTPVENDOR}" 2>/dev/null | ${SED} -n '/strong>[ ]*MAC Address/,/<\/pre>/ p' | ${GREP} -v '>' | ${TR} -s ' ' )
     ${ECHO} "Interface: ${INTERFACE}  Vendor: ${LOOKUP}"
  done
}

get_interfaces
get_vendors

exit 0

Ran this on a few of my Linux systems:

Code:

# ./get_nic_vendor.sh 
Interface: eth0  Vendor:  00144F Sun Microsystems, Inc
Interface: eth1  Vendor:  00144F Sun Microsystems, Inc
Interface: eth2  Vendor:  00144F Sun Microsystems, Inc
Interface: eth3  Vendor:  00144F Sun Microsystems, Inc
# ./get_nic_vendor.sh 
Interface: eth0  Vendor:  009027 intel corporation
# ./get_nic_vendor.sh 
Interface: eth0  Vendor:  000D56 Dell PCBA Test
Interface: eth1  Vendor:  000D56 Dell PCBA Test

Cheers,
ZB

net_phylookup

net_phylookup(9F)					   Kernel Functions for Drivers 					 net_phylookup(9F)

NAME

       net_phylookup - determine if a network interface name exists for a network protocol

SYNOPSIS

       #include <sys/neti.h>

       phy_if_t net_phylookup(const net_data_t net, const char *name);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       net     value returned from a successful call to net_protocol_lookup(9F).

       name    name of the network interface to find.

DESCRIPTION

       The net_phylookup() function attempts to resolve the interface name passed in with the network protocol.

       When  called  successfully, the value returned represents a network interface that exists, at the time of the call, within the scope of the
       network interface. This value is only guaranteed to be unique for a name within the scope of the network protocol.

RETURN VALUES

       The net_phylookup() function returns -1 if it is not supported by the network  protocol,  and 0 if the named  network  interface  does  not
       exist  (or is otherwise	unknown).  Otherwise, it returns  a  value  greater  than 0 representing a network interface that currently exists
       within the scope of this network protocol.

CONTEXT

       The net_phylookup() function may be called from user,  kernel, or interrupt context.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
