Hi Rafael,
Which kernel do i need for this feature? I have a mini-itx board
combined with a daughterboard with additionally 3xRJ45, so that i have 4
network devices:
...
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
04:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8110SC/8169SC Gigabit Ethernet (rev 10)
04:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8110SC/8169SC Gigabit Ethernet (rev 10)
04:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8110SC/8169SC Gigabit Ethernet (rev 10)
Not all of them are used at the same time. So how can i put the unused
in a low power state?
regards Markus
