Title: Network lost after long sleep Status in linux package in Ubuntu: Incomplete Bug description: Hello, After a long time in sleep mode, my Desktop running Ubuntu 20.04 loses its network ethernet link. the demsg shows the following lines after sleep exit: [10402.613687] PM: suspend exit [10403.035311] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) [10403.121362] ata1.00: configured for UDMA/133 [10403.363882] e1000e: enp0s25 NIC Link is Down [10406.484276] e1000e: enp0s25 NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx [10406.484281] e1000e 0000:00:19.0 enp0s25: 10/100 speed: disabling TSO [10406.484322] IPv6: ADDRCONF(NETDEV_CHANGE): enp0s25: link becomes ready the ethernet is up but at 10 M / full duplex DHCP of my router does not give any address. the only way to retrieve a Full 1000 M functionnal link is to reboot the machine. Can't determine how much time of sleep it needs to reproduce, since an immediate sleep/wake-up does not produce network loss.
