[PATCH 0/5] realtek: avoid blocking for too long

[Jan Hoffmann]

This fixes multiple instances where the realtek drivers may block for
too long. These issues were discovered on HPE 1920 devices where such
behaviour is made obvious by the short timeout of the hardware watchdog.

This patch series intentionally doesn't address calls to pr_debug which
may also block for long enough to cause issues. Those calls are only
effective if the kernel is built with support for debug messages, which
is a non-default configuration. Also, it is really an issue with printk
itself and in no way specific to the realtek drivers. It is already
being worked on upstream by moving to threaded printk.

Jan Hoffmann (5):
  realtek: avoid busy waiting for RTL839x PHY read/write
  realtek: simplify log messages in rtl83xx_mdio_probe
  realtek: add debugfs node for L2 table
  realtek: reduce excessive logging for FDB operations
  realtek: restructure rtl_table_read/write
