[dpdk-dev] Change ether_addr to avoid conflict

[Lewis Donzis]

Please consider changing “struct ether_addr” in rte_ether.h to “struct rte_ether_addr”, in order to avoid conflicts with the same structure name /usr/include/net/ethernet.h.

This is kind of a pain for us since we would like to include ethernet.h in order to get some other definitions, but we can’t because it conflicts with the same structure name in rte_ether.h.

Thanks,
lew

I agree, but it will require a deprecation notice as a lot of code uses it.

Yes, it is a very long standing issue.

During the last technical board meeting, we discussed a plan to fix it:

Please consider changing "struct ether_addr" in rte_ether.h to "struct rte_ether_addr", in order to avoid conflicts with the same structure name /usr/include/net/ethernet.h.

Sometimes, there is need to include /usr/include/net/ethernet.h, but it conflicts with the same structure name in rte_ether.h.  Was there a reason this structure wasn't given the standard rte_ prefix?

Thanks,

Only history, remember EAL was first running on bare metal.

Changing to 'struct rte_ether_addr' breaks source of lots of applications.
