  Those commands date back to the early stages of DPDK when only PCI
devices were supported.
At the time, developers may have used those commands to help in
debugging their buggy^Wwork in progress drivers.

Removing them, we can drop the dependency on the PCI bus and library and
make testpmd bus agnostic.

-Register Functions
-------------------
-
-The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
-This is mainly useful for debugging purposes.
-Reference should be made to the appropriate datasheet for the network card for details on the register addresses
-and fields that can be accessed.
-
-read reg
-~~~~~~~~
-
-Display the value of a port register::
-
-   testpmd> read reg (port_id) (address)
-
-For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel 82599 10 GbE Controller::
-
-   testpmd> read reg 0 0xEE00
-   port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
-
-read regfield
-~~~~~~~~~~~~~
-
-Display a port register bit field::
-
-   testpmd> read regfield (port_id) (address) (bit_x) (bit_y)
-
-For example, reading the lowest two bits from the register in the example above::
-
-   testpmd> read regfield 0 0xEE00 0 1
-   port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)
-
-read regbit
-~~~~~~~~~~~
-
-Display a single port register bit::
-
-   testpmd> read regbit (port_id) (address) (bit_x)
-
-For example, reading the lowest bit from the register in the example above::
-
-   testpmd> read regbit 0 0xEE00 0
-   port 0 PCI register at offset 0xEE00: bit 0=1
-
-write reg
-~~~~~~~~~
-
-Set the value of a port register::
-
-   testpmd> write reg (port_id) (address) (value)
-
-For example, to clear a register::
-
-   testpmd> write reg 0 0xEE00 0x0
-   port 0 PCI register at offset 0xEE00: 0x00000000 (0)
-
-write regfield
-~~~~~~~~~~~~~~
-
-Set bit field of a port register::
-
-   testpmd> write regfield (port_id) (address) (bit_x) (bit_y) (value)
-
-For example, writing to the register cleared in the example above::
-
-   testpmd> write regfield 0 0xEE00 0 1 2
-   port 0 PCI register at offset 0xEE00: 0x00000002 (2)
-
-write regbit
-~~~~~~~~~~~~
-
-Set single bit value of a port register::
-
-   testpmd> write regbit (port_id) (address) (bit_x) (value)
-
-For example, to set the high bit in the register from the example above::
-
-   testpmd> write regbit 0 0xEE00 31 1
-   port 0 PCI register at offset 0xEE00: 0x8000000A (2147483658)
