[dpdk-dev] [PATCH v2 1/4] kni: fix build with kernel 3.8

[Thomas Monjalon <thomas.monjalon@6wind.com>]

- timecompare (used for hardware timestamping) has been removed.
(see Linux commit 65f8f9a1c1db831e5159e3e3e50912d1f214cd0c)
Simply disable HW_TIME_STAMP feature because it is not used by KNI.
For this purpose, kcompat.h must be included before testing for
HAVE_HW_TIME_STAMP.

- annotations __devinit and __devexit have been removed.
(see Linux commit 54b956b903607f8f8878754dd4352da6a54a1da2)
