Subject: [dpdk-dev] [PATCH v6] examples: fix RSS hash function configuration

ethdev layer introduced checks for application requested RSS hash functions and 
returns error for ones unsupported by hardware

This check breaks some sample applications which blindly configures RSS hash 
functions without checking underlying hardware support.

Updated examples to mask out unsupported RSS has functions during device 
configuration.
Prints a log if configuration values updated by this check.

BSD

FreeBSD does not support running multiple primary processes concurrently, 
because all DPDK instances will allocate memory from the same place (memory 
provided by contigmem driver).
While it is technically possible to launch a DPDK process using no-shconf 
switch, it will actually corrupt main process'
for the above reason.

Fix EAL flags autotest to not run primary processes unless both no-shconf and 
no-huge are specified.

Subject: [dpdk-dev] [PATCH v2] app/testpmd: fix dcb config failure

After adding RSS hash offload check, default rss_hf will fail on devices that 
do not support all bits. This will lead to dcb config failure. The patch fixes 
this issue by reading current valid rss_conf from the device.

Subject: [dpdk-dev] [PATCH] eal/bsd: silence not supported error in interrupts

Currently, nic_uio driver does not support interrupts, so any attempts to 
install an interrupt handler will fail with a not supported error, which will 
cause an error message that is confusing to the user.

Silence this error by moving it to debug log level, and reword the message to 
avoid containing the word "Error", to avoid triggering DTS test failures [1].
