lan743x: Fix TX Stall Issue

2019-03-01T19:34:09+00:00

It has been observed that tx queue stalls while downloading
from certain web sites (example www.speedtest.net)

The cause has been tracked down to a corner case where
dma descriptors where not setup properly. And there for a tx
completion interrupt was not signaled.

This fix corrects the problem by properly marking the end of
a multi descriptor transmission.

enc28j60: Correct description of debug module parameter

2019-02-27T17:35:24+00:00

The netif_msg_init() API takes on input the amount of bits to be set. The
description of debug parameter in the enc28j60 module is misleading in this
sense and passing 0xffff does not give an expected behaviour.

Fix the description of debug module parameter to show what exactly is expected.

lan743x: Remove phy_read from link status change function

2019-01-08T21:26:12+00:00

It has been noticed that some phys do not have the registers
required by the previous implementation.

To fix this, instead of using phy_read, the required information
is extracted from the phy_device structure.

lan743x: Remove MAC Reset from initialization

2018-12-19T23:48:11+00:00

The MAC Reset was noticed to erase important EEPROM settings.
It is also unnecessary since a chip wide reset was done earlier
in initialization, and that reset preserves EEPROM settings.

There for this patch removes the unnecessary MAC specific reset.

lan743x: Expand phy search for LAN7431

2018-12-19T05:35:56+00:00

The LAN7431 uses an external phy, and it can be found anywhere in
the phy address space. This patch uses phy address 1 for LAN7430
only. And searches all addresses otherwise.

lan743x: Enable driver to work with LAN7431

2018-11-28T00:32:07+00:00

This driver was designed to work with both LAN7430 and LAN7431.
The only difference between the two is the LAN7431 has support
for external phy.

This change adds LAN7431 to the list of recognized devices
supported by this driver.

Updates for v2:
    changed 'fixes' tag to match defined format

lan743x: fix return value for lan743x_tx_napi_poll

2018-11-28T00:29:24+00:00

The lan743x driver, when under heavy traffic load, has been noticed
to sometimes hang, or cause a kernel panic.

Debugging reveals that the TX napi poll routine was returning
the wrong value, 'weight'. Most other drivers return 0.
And call napi_complete, instead of napi_complete_done.

Additionally when creating the tx napi poll routine.
Changed netif_napi_add, to netif_tx_napi_add.

Updates for v3:
    changed 'fixes' tag to match defined format

Updates for v2:
use napi_complete, instead of napi_complete_done in
    lan743x_tx_napi_poll
use netif_tx_napi_add, instead of netif_napi_add for
    registration of tx napi poll routine

lan743x: Remove SPI dependency from Microchip group.

The SPI dependency does not apply to lan743x driver, and other
