Flex parser is a HW parser that can support protocols that are not
natively supported by the HCA, such as Geneve (TLV options) and GTP-U.
There are 8 such parsers, and each of them can be assigned to parse a
specific set of protocols.
This patch adds misc4 match params which allows using a correct flex parser
that was programmed to the required protocol.

net: Korina improvements

While converting Mikrotik RB532 support to use device tree I stumbled
over the korina ethernet driver, which used way too many MIPS specific
hacks. This series cleans this all up and adds support for device tree.

Changes in v6:
 - remove korina from resource names and adapt DT binding to it
 - removed superfluous braces around of_get_mac_address

Changes in v5:
  - fixed email address in binding document, which prevented sending it

Changes in v4:
  - improve error returns in mdio_read further
  - added clock name and improved clk handling
  - fixed binding errors

Changes in v3:
  - use readl_poll_timeout_atomic in mdio_wait
  - return -ETIMEDOUT, if mdio_wait failed
  - added DT binding and changed name to idt,3243x-emac
  - fixed usage of of_get_mac_address for net-next

Changes in v2:
  - added device tree support to get rid of idt_cpu_freq
  - fixed compile test on 64bit archs
  - fixed descriptor current address handling by storing/using mapped
    dma addresses (dma controller modifies current address)
