kni: fix build with kernel < 2.6.35 and vhost debug enabled

RHEL6.5 kernel is based on 2.6.32. But there are two changing
from 2.6.35:
1. socket struct is changed
It wrappered previous wait_queue_head_t of socket to
struct socket_wq. So for the kernel older than 2.6.35, we should
directly use socket->wait instead.

2. new function sk_sleep()
This function is implemented from 2.6.35 to obtain wait queue
from struct sock. This patch adds a macro in kni/compat.h
to be compatible with older kernels.

Patch is tested in RHEL6.5 and RHEL7.0 with:
CONFIG_RTE_LIBRTE_KNI=y
CONFIG_RTE_KNI_KO_DEBUG=y
CONFIG_RTE_KNI_VHOST=y

Then commit 815cfb7925bb6de ("fix link of combined shared library using CC")
introduced another prefixing of CPU_LDFLAGS in rte.sharelib.mk,
included in lib/Makefile.
Because CPU_LDFLAGS is an exported variable, the prefixing is done twice.

app/testpmd: fix macro check for little endian

Compiling with clang on FreeBSD gave a compilation error:
app/test-pmd/csumonly.c:84:5: fatal error: '__BYTE_ORDER' is not defined, evaluates to 0 [-Wundef]

Querying the preprocessor defines show both the define and value used
are incorrect.
$ clang -dM -E - < /dev/null | grep BYTE
\#define  __BYTE_ORDER__  __ORDER_LITTLE_ENDIAN__

Changing the check to  __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__ then
resolves the issue.

app/testpmd: fix out-of-range error on bsd

The definition value for IPPROTO_DIVERT protocol uses a value
which is out of range of the uint8_t type, giving clang compiler
errors on FreeBSD.

app/test-pmd/icmpecho.c:231:7: fatal error: overflow converting case value
        to switch condition type (258 to 2) [-Wswitch]
                case IPPROTO_DIVERT: /**< divert pseudo-protocol */

This is fixed by having the code to return the protocol name
use the uint16_t type for the protocol value input.

10 years agomk: fix linking with some linux toolchains

mk: fix linking with some linux toolchains

Ubuntu/Debian toolchain passes --as-needed flag to the linker by default.
Add --no-as-needed flag by default in linuxapp exec-env to ensure correct
linking.

The problem arises because librte_eal doesn't add a DT_NEEDED entry for
librte_mempool despite the fact that it references symbols in that library.
It does this because we don't explicitly link with -lrte_mempool when we
build librte_eal.
