ethernet: replace netdev->dev_addr assignment loops

2021-10-14T16:22:25+00:00

A handful of drivers contains loops assigning the mac
addr byte by byte. Convert those to eth_hw_addr_set().

net: use dev_addr_set()

2021-10-09T10:55:01+00:00

Use dev_addr_set() instead of writing directly to netdev->dev_addr
in various misc and old drivers.

atm: Use list_for_each_entry() to simplify code in resources.c

2021-06-10T21:08:09+00:00

Convert list_for_each() to list_for_each_entry() where
applicable. This simplifies the code.

net: atm: use DEVICE_ATTR_RO macro

which makes the code a bit shorter and easier to read.

This converts the driver to use the new tasklet API introduced in

net: atm: pppoatm: use tasklet_init to initialize wakeup tasklet

2021-01-30T02:24:05+00:00

Previously a temporary tasklet structure was initialized on the stack
using DECLARE_TASKLET_OLD() and then copied over and modified. Nothing
else in the kernel seems to use this pattern, so let's just call
tasklet_init() like everyone else.

atm: nicstar: Replace in_interrupt() usage

2020-11-19T00:43:55+00:00

push_scqe() uses in_interrupt() to figure out if it is allowed to sleep.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

Aside of that in_interrupt() is not correct as it does not catch preempt
disabled regions which neither can sleep.

ns_send() (the only caller of push_scqe()) has the following callers:

- vcc_sendmsg() used as proto_ops::sendmsg is expected to be invoked in
  preemtible context.
  -> vcc->dev->ops->send() (ns_send())

- atm_vcc::send via atmdev_ops::send either directly (pointer copied by
  atm_init_aal34() or atm_init_aal5()) or via atm_send_aal0().
  This is invoked by drivers (like br2684, clip, pppoatm, ...) which are
  called from net_device_ops::ndo_start_xmit with BH disabled.

Add atmdev_ops::send_bh which is used by callers from BH context
(atm_send_aal*()) and if this callback missing then ::send is used
instead.
Implement this callback in nicstar and use it to replace in_interrupt().
