Building the r8168 driver for RealTek RTL8168B/8111B, RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D, DP/8111DP, and RTL8168E/8111E Gigabit Ethernet controllers with PCI-Express interface.

* kerver=`uname -r` && wget http://tinycorelinux.net/`version -m`.x/`uname -m`/release/src/kernel/linux-${kerver%-*}-patched.txz
  (~120MB download)
* sudo mkdir /lib/modules/`uname -r`/build && cd /lib/modules/`uname -r`/build
  -Alternatively unpack on a mounted disk partition and symlink to /lib/modules/`uname -r`/build so files not lost on reboot.

* Unpack driver source archive somewhere
* Enter driver source directory and run: make modules
* cd src
* r8168.ko is the kernel module
* strip module debugging symbols with: strip --strip-unneeded r8168.ko
* gzip r8168.ko

#config (manual):

* Add "blacklist=r8169" bootcode to bootloader parameters list to prevent the other driver from automatically loading at boot.
* Add "insmod /usr/local/lib/modules/`uname -r`/kernel/drivers/net/ethernet/realtek/r8168.ko.gz" command to /opt/bootlocal.sh

#Making an extension:

* mkdir -p r8168/usr/local/lib/modules/`uname -r`/kernel/drivers/net/ethernet/realtek
* cp ../r8168-master/src/r8168.ko.gz r8168/usr/local/lib/modules/`uname -r`/kernel/drivers/net/ethernet/realtek/
