ff5c396001 i40e/base: fix build with clang
When compiling with clang, it detects that a variable used for debug
is unused (debug_mask is never set):
    lib/librte_pmd_i40e/i40e/i40e_nvm.c:708:20: error: unused variable
          'i40e_nvm_update_state_str' [-Werror,-Wunused-variable]
    STATIC const char *i40e_nvm_update_state_str[] = {
                       ^
As we are not supposed to modify the base driver (except for update
synchronization from Intel), it was ignored with GCC thanks to the
option -Wno-unused-variable but clang was forgotten.

The FW for SW3E is incorrectly reporting a breakout cable as PHY
type 0x3 when it should be 0x16 (I40E_PHY_TYPE_10GBASE_SFPP_CU).
As this is supposed to be fixed in the next FW version
(FW versions >= 4.4), if we get this value back from FW and the
version is < 4.4, reassign it to I40E_PHY_TYPE_10GBASE_SFPP_CU.

2450cc2dc8 i40e/base: find partition id in NPAR mode and disable FCoE
In NPAR mode the driver instance might be controlling the base
partition or one of the other "fake" PFs. There are some things
that can only be done by the base partition, aka partition_id 1.
This code does a bit of work to find how many partitions are there
in per port and what is the current partition_id. In addition,
FCOE is disabled by default, as it was pushed out from the firmware.

12b116260b i40e/base: fix hardware port number for pass-thru
Getting the pf_id from the function number was a good place to
start, but when the PF was setup in pass-thru mode, the PCI
bus/device/function was virtualized and the number in the VM is
different from the number in the bare metal. This caused HW
configuration issues when the wrong pf_id was used to set up the
HMC and other structures. The PF_FUNC_RID register has the real
bus/device/function information as configured by the BIOS, so use
that for a better number.

16c979f9ad i40e: disable setting of PHY configuration
There was a known link issue on 40G ports on NVM version (FVL3E),
when setting phy configuration. As a workaround, setting of phy
configuration should be disabled. The impact is that the link cannot
be forcedly configured, which doesn't affect any feature functions.
The workaround can be removed when a formal fix is ready later.

501a9459c2 mk: simplify conditions for libs to link
Simplify the ifdefs in rte.app.mk to make the code more
readable and maintainable by introducing a internal
_LDLIBS-y variable to build up the LDLIBS variable.

The new internal variable _LDLIBS-y should not be
used outside of the rte.app.mk file.

159793ac86 vhost: fix virtio freeze due to missed interrupt
Update of used->idx and read of avail->flags could be reordered.
Memory fence should be used to ensure the order, otherwise guest could see
a stale used->idx value after it toggles the interrupt suppression flag.
After guest sets the interrupt suppression flag, it will check if there
is more buffer to process through used->idx. If it sees a stale value,
it will exit the processing while host won't send interrupt to guest.

3f313bef34 eal/linux: fix irq handling with igb_uio
The introduction of uio_pci_generic broke interrupt handling with
igb_uio. The igb_uio device uses the kernel read/write method to
enable disable IRQ's; the uio_pci_generic has to use PCI intx
config read/write to enable disable interrupts.

Since igb_uio uses MSI-X the PCI intx config read/write won't
work.

Fixes: c112df6875 ("eal/linux: toggle interrupt for uio_pci_generic")

8c0eca54cd scripts: fix build in a symlinked directory
The script relpath.sh returns the relative path of the first directory
from the second directory. It is used to generate relative symlinks,
which can be useful if the build directory is embedded in the dpdk
directory: the whole dpdk can be moved without breaking the links,
which is helpful for an installation.

In case the build directory is a symlink, the script was not generating
the proper relative path. Fix this by calling "readlink -f" on the
arguments.
