[PATCH 1/3] raw/ioat: fix build error for missing errno

[Bruce Richardson]

The inline functions in rte_idxd_rawdev_fns.h make use of rte_errno, but
the header with its definition is not included by that file leading to
build errors.

[PATCH 2/3] raw/ioat: fix build when ioat dmadev enabled

[Bruce Richardson]

The build of the raw/ioat driver only occurs when the equivalent dmadev
drivers are disabled. Complications occur when the ioat dmadev is being
built but not the idxd. In this case, only the idxd part of raw/ioat
gets built, but the definition of the logtype is in the ioat part,
causing build errors.

  .../raw_ioat_idxd_bus.c.o: In function `idxd_vdev_mmap_wq':
  idxd_bus.c:(.text+0x116): undefined reference to `ioat_pmd_logtype'

Fix this by moving the logtype definition to the common C file, and
renaming it to avoid conflicts with a similarly named value in the
dma/ioat driver.
