[PATCH V4 00/15 net-next] qca_spi: collection of improvements

[Stefan Wahren]

This series contains a wild collection of improvements for the
qca_spi driver. This is a follow-up series to the recent bugfixes [1].

Patch 1, 2 & 3 in this series is the initially intended rework of
netdev_open/close. Patch 4 & 10 are minor functional improvements and
the rest is clean-up.

Changes in V4:
- keep thread handling in netdev_open, but improve this by two
  separate patches ( 1 & 2 )
- add missing link to bugfix series

Changes in V3:
- rebase on net-next-20240124
- improve commit message in Patch 8
- add Reviewed-by's from Jacob Keller
- add Patch 13 for mailmap as suggested by Jacob
- add Patch 14 for MAINTAINERS entry

Changes in V2:
- rebase on net-next-20231218
- improve cover letter

[PATCH V4 01/15 net-next] qca_spi: Add check for kthread_stop

[Stefan Wahren]

We better not rely on that spi_thread points to a running
thread. So add an check for this.

[PATCH V4 02/15 net-next] qca_spi: Improve SPI thread creation

[Stefan Wahren]

Directly storing the result of kthread_run within the private
driver data makes it harder to identify if the pointer has a
running thread or not. So better use a local variable for
the result check and we don't have to care about error pointer
in the rest of the code.

[PATCH V4 03/15 net-next] qca_spi: Improve SPI IRQ handling

[Stefan Wahren]

The functions qcaspi_netdev_open/close are responsible of request &
free of the SPI interrupt, which wasn't the best choice because
allocation problems are discovered not during probe. So let us split
IRQ allocation & enabling, so we can take advantage of a device
managed IRQ.

[PATCH V4 04/15 net-next] qca_spi: Avoid skb_copy_expand in TX path

[Stefan Wahren]

The skb spare room needs to be expanded for SPI header, footer
and possible padding within the TX path. So announce the necessary
space in order to avoid expensive skb_copy_expand calls.

Currently qca_spi reserves enough space for 4 complete Ethernet over SPI
frames in the receive buffer. Unfortunately this is hidden under a magic
number. So replace it with a more self explaining define.

[PATCH V4 09/15 net-next] qca_spi: Improve calculation of RX buffer size

[Stefan Wahren]

There are two points with the calculation of RX buffer size which are
not optimal:
1. dev->mtu is a mutual parameter and it's currently initialized with
   QCAFRM_MAX_MTU. But for RX buffer size calculation we always need the
   maximum possible MTU. So better use the define directly.
2. This magic number 4 represent the hardware generated frame length
   which is specific to SPI. We better replace this with the suitable
   define.

There is no functional change.
