Subject: kernel: provide kmod-fixed-phy as separate kmod
X-Git-Tag: mikrotik~290
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3fabca88944e736176310be06e97f0f3cc9010cb;p=openwrt%2Fstaging%2Fchunkeey.git

kernel: provide kmod-fixed-phy as separate kmod

Almost all targets have the fixed-phy feature built into the kernel.
One big exception is x86. This caused a problem with the upcoming
LAN78xx usb driver. Hence this patch breaks out the fixed-phy from
of_mdio (which didn't include the .ko) and puts into a separate
module.
