[PATCH 00/11] rtlwifi: rtl_pci: Update mini driver for RTL8822BE

[PATCH 00/11] rtlwifi: rtl_pci: Update mini driver for RTL8822BE

[Larry Finger]

These changes are for the 4.15 stream.

The modifications implement nearly all the changes needed to allow the
RTL8822BE in staging to use rtl_pci in the wireless tree. The only
exceptions are related to BT coexistence, which will be added once btcoex
is updated.

Once these patches reach mainline, I will submit a patch to staging that
changes r8822be to use the standard rtl_pci, and deletes the duplicated
code.

[PATCH 03/11] rtlwifi: rtl_pci: Simplify some code be eliminating extraneous variables

[Larry Finger]

In several places, the code assigns a variable inside an "if" or "case"
block, but uses it only once. The code is simplified by eliminating
the extraneous variable. With this change, one level of indenting is
saved.

This patch does not cause any functional changes in the binary code.

[PATCH 07/11] rtlwifi: rtl_pci: Extend recognized interrupt parameters from two to four ISR

[Larry Finger]

From: Ping-Ke Shih <pkshih@realtek.com>

8822be checks H2CQ by int_d, so we extend to four ISR.
Also, irq_mask is extended to four.

[PATCH 08/11] rtlwifi: rtl_pci: Refactor TX/RX flow

[Larry Finger]

From: Steven Ting <steventing@realtek.com>

After this refactoring, the variables wp and rp in TX ring can only be
updated in OP_TX and TX_OK respectively without protection. The other
changes are listed below:

1. remove avl_desc from TX ring, because it can be calculated by wp and rp.
   Moreover, we update this variable in op_tx (thread context) and TX_OK
   (BH context) without protection.
2. extend calc_fifo_space(rp, wp) to calc_fifo_space(rp, wp, size), and fix
   the caller's parameter 'size'.
3. Get RX remaining counter only if it count down to zero.
4. remove available_desc check from Tx ISR

[Larry Finger]

From: Tsang-Shian Lin <thlin@realtek.com>

AP WiFi settings are changed(channel, bandwidth), but deauth may not
received by STA. For these cases, we need to detect and handle beacon
changes.

[PATCH 11/11] rtlwifi: rtl_pci: Fix the bug when inactiveps is enabled.

[Larry Finger]

From: Tsang-Shian Lin <thlin@realtek.com>

Reset the driver current tx read/write index to zero when inactiveps
nic off to sync with HW state. Wrong driver tx read/write index will
cause Tx fail.

In the future you might want to convert this to a struct which is a lot
easier to handle. But no need to resend because of this.

Re: [PATCH 08/11] rtlwifi: rtl_pci: Refactor TX/RX flow

Why? Try to always answer that, that's the most important part of the
commit log. Are you fixing a bug (if yes, describe it briefly), is this
just code cleanup or what's your motivation to change the code?

One logical change per patch, please. One good rule of thumb is that if
you have to list the changes made in patch you need to split the patch.
