Subject: [PATCH 1/2] wifi: rtl8xxxu: Support new chip RTL8188EU
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
Precedence: bulk

From: Jes Sorensen <Jes.Sorensen@gmail.com>

This chip is found in cheap USB devices from TP-Link, D-Link, etc.

Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.

Chip versions older than "I cut" need software rate control. That will
be in the next commit. Until then MCS7 is used for all data frames.

The "I cut" chips are not supported. They require different firmware
and initialisation tables. Support can be added if someone has the
hardware to test it.

So this patch is 52 of the 57 patches found here, squashed together:
https://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git/log/drivers/net/wireless/realtek/rtl8xxxu?h=rtl8xxxu-8188eu

Starting from c3f84ded6f76 ("rtl8xxxu: Accept firmware signature 0x88e0")
up to a9b05c059510 ("rtl8xxxu: Add rpt_sel entry to struct rtl8xxxu_rxdesc16").

These patches were not needed:
3170622ccb61 ("rtl8xxxu: Detect 8188eu parts correctly")
8fb5bc92bce0 ("rtl8xxxu: Initialize GPIO settings for 8188eu")
6ab646adb585 ("rtl8xxxu: Implement rtl8188e_set_tx_power()")
2ccd1f1fc480 ("rtl8xxxu: properly detect RTL8188EU devices")
809a2e000cab ("rtl8xxxu: Do not set auto rate fallback on 8188eu")

On top of that, I made various changes required for today's kernel,
plus changes to match the newer vendor driver more closely, plus some
bug fixes.
