 Greetings!
 
 Sorry Martin, but after trying the patch, I have to report it did not fix t=
 he=20
 problem. although it did significantly change the erroneous behaviour :)
 
 Now ifconfig can see if the network cable is plugged in, or not, but other=
 =20
 tools cannot. I did try ifwatchd and dhcpcd, and both believe that the=20
 interface is always down. To complicate, dhcpcd could not bring it up (for=
 =20
 longer than a wink of an eye) either, not even with the -K (disable link=20
 status detection) switch!
 
 Pasting simultaneous dhcpcd and ifwatchd run outputs:
 
 dhcpcd:=20
