This code is dead from the moment we switched to meson, because
RTE_LIBRTE_IXGBE_BYPASS is never defined at build time.
There was no complaint about the loss of those commands, drop all
associated code and documentation.

'RTE_LIBRTE_IXGBE_BYPASS' is hardcoded in the 
'drivers/net/ixgbe/meson.build'.
And for testpmd, macro can be enabled by argument to meson,
'-Dc_args=-RTE_LIBRTE_IXGBE_BYPASS'.

If ixgbe bypass mode agreed to remove, we can remove it, but I think 
above build time flag justification is not sufficient to remove it.
