- In qede_mac_addr_set(), in order to configure default MAC address we
first delete the existing MAC address before trying to add new one. During
init time, there is no MAC filter to begin with, so trying to remove a
non-existing MAC address causes a firmware exception. This can be prevented
by internally calling qede_mac_addr_add() which has the checks in place to
delete a MAC address only if it was added before.
- Remove setting of the default MAC address from within

C++ does not support the C99-style designated initializers used in this
file for the default item masks. While the resulting symbols are primarily
useful to PMDs (written in C), they are exposed as part of the public API
for documentation purposes and to assist application writers.
Considering that:
- using pre-C99 initialization style for compatibility with C++ would
render them difficult to understand (all struct members must be
initialized)
- using both initialization styles would be needlessly verbose
- not exposing them at all would defeat their purpose
- applications do not normally need these symbols at run time
This commit hides these symbols from C++ applications. Specific C++
initializers will be added later if necessary.

armv8 implementations may have 64B or 128B cache line.
Setting to the maximum available cache line size in generic config to
address minimum DMA alignment across all arm64 implementations.
Increasing the cacheline size has no negative impact to cache invalidation
on systems with a smaller cache line.
The need for the minimum DMA alignment has impact on functional aspects
of the platform so default config should cater the functional aspects.
There is an impact on memory usage with this scheme, but that's not too
important for the single image arm64 distribution use case.

On i686 builds, the uin64_t type is 64-bits in size but is aligned to
32-bits only. This causes mbuf fields for rearm_data to not be 16-byte
aligned on 32-bit builds, which causes errors with some vector PMDs which
expect the rearm data to be aligned as on 64-bit.
Given that we cannot use the extra space in the data structures anyway, as
it's already used on 64-bit builds, we can just force alignment of the
physical address in the mbuf to 8-bytes in all cases. This has no effect on
64-bit systems, but fixes the updated PMDs on 32-bit.
