It seems to me that your problem is in your control mechanisms, specifically that your if statement should be inside of a while statement that goes through your data line by line. Also maybe a global variable to keep track of matches. If you're reading a file, then you'll have something like:

my $matches = 0;
open FILE, ">filename.txt" or die $!;
while (my $ethernet = <FILE>) {

if ($ethernet=~/eth1\.\d{4}\@/m){
  ## do something
  matches++;
}

}
