From c6603687564769ab3aff630da958c1790571ef0d Mon Sep 17 00:00:00 2001 From: rohitsuman86 Date: Wed, 27 Jun 2018 23:21:21 +0530 Subject: [PATCH] Update README.md 1) Updated the documentation to make it noob friendly. 2) Added commands for Ubuntu as well as Fedora OS. 3) Specified at top of the file that even though these drivers are patched for Linux kernel up till 4.15, they do work with the latest Linux Kernel 4.17 too!! ( I just installed it in my updated Fedora 28 system with Linux 4.17.2, so I know. I'm not sure about 4.16 though. ) --- README.md | 131 +++++++++++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 119 insertions(+), 12 deletions(-) diff --git a/README.md b/README.md index 97123df..2f9a7eb 100644 --- a/README.md +++ b/README.md @@ -1,5 +1,7 @@ # rtl8192eu linux drivers +These drivers are patched to work with Linux Kernels up till 4.15 but they work fine with Linux Kernel 4.17.x too. + **NOTE:** This branch is based on Realtek's driver versioned 4.4.1. `master` is based on 4.3.1.1 originally.
