Hi,
I'm using linux 2.6.14.3 with swsusp2 2.2rc14 (not the most new ones).
Since I'm using NetworkManager, which switches and manages my wired and
wireless devices, I have to reload 8139too after resume, before plugin
events of wired network are recognized. Some other users of NM are
reporting similar problems.
I assume that either is suspending in 8139too or in mii not working
properly. Following is some data, I collected so far.
eth1 is my wired, using 8139too from 2.6.14.3:
after resume and NM wake up
mobile ~ # ifplugstatus -v
eth1:
SIOCETHTOOL: unplugged
SIOCGMIIPHY failed (Invalid argument)
Wireless failed.
IFF_RUNNING: unplugged
SIOCDEVPRIVATE failed (Invalid argument)
mobile ~ # cat /sys/class/net/eth1/carrier
cat: /sys/class/net/eth1/carrier: Invalid argument

Index #1: Found a RealTek RTL8139 adapter at 0x4000.
Realtek station address 00:00:f0:92:f7:5f, chip type 'rtl8139C+'.
Receiver configuration: Reception disabled
Rx FIFO threshold 16 bytes, maximum burst 16 bytes, 8KB ring
Transmitter disabled with normal settings, maximum burst 16 bytes.
Flow control: Tx enabled Rx enabled.
The chip configuration is 0x10 0x1d, MII half-duplex mode.
No interrupt sources are pending.
The RTL8139 does not use a MII transceiver.
It does have internal MII-compatible registers:
Basic mode control register 0x3100.
Basic mode status register 0x7809.
Autonegotiation Advertisement 0x01e1.
Link Partner Ability register 0x0000.
Autonegotiation expansion 0x0000.
Disconnects 0x0000.
False carrier sense counter 0x0000.
NWay test register 0x0404.
Receive frame error count 0x0000.

then, after restarting NM or reloading 8139too:
mobile ~ # ifplugstatus -v eth1
eth1:
SIOCETHTOOL: link beat detected
SIOCGMIIPHY: link beat detected
Wireless failed.
IFF_RUNNING: link beat detected
SIOCDEVPRIVATE failed (Operation not supported)
mobile ~ # cat /sys/class/net/eth1/carrier

-------------------------
difference in rtl8139-daig -mm
Receiver configuration: Unicast and no multicast
Rx FIFO threshold 2048 bytes, maximum burst 2048 bytes, 32KB ring
Transmitter enabled with NONSTANDARD! settings, maximum burst 1024 bytes.
Any hints? Is this a bug or a configuration issue?
