However, Port Virtualizer mode is not initialized in DPDK, so X710 will

Interestingly, clang and gcc has different prototype for _mm_prefetch().
For gcc, we have
_mm_prefetch (const void *__P, enum _mm_hint __I)
While for clang, it's
#define _mm_prefetch(a, sel) (__builtin_prefetch((void *)(a), 0, (sel)))
That's how the following error comes with clang:
error: cast from 'const void *' to 'void *' drops const qualifier

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object

The standard Virtual Ethernet Bridge(VEB) definition in 1Qbg is a bridge

Instead, traffic can be sent from one VF to another using the floating

This patch adds floating VEB options in the devargs for i40e driver.
Using these parameters, applications can decide whether to use legacy
VEB/VEPA or a floating VEB.
To enable this feature, the user should pass a devargs parameter to the
EAL, for example "-w 84:00.0,enable_floating_veb=1", to control whether
the PMD will to use the floating VEB feature or not.
Once the floating VEB feature is enabled, all the VFs created by
