[dpdk-dev] [PATCH 11/22] net/ena/base: adjust changes to lastest ena-com

[Michal Krawczyk <mk@semihalf.com>]

From: Amit Bernstein <amitbern@amazon.com>

1. As memzone uses unique names, changed alloc coherent macro to use
   64 bit size atomic variable to increase the memzone name space
2. "handle" param name change to be consistent with other macros
3. Variable definition displacement
4. Backslash alignment to column 80
