It seems compilation time of drivers/event/cnxk is getting very long. Please could you look at it?

Hi Thomas, Ferruh,

We need to further split Rx/Tx functions in both net/cnxk and event/cnxk to enable more parallelism.
This is planned for the next release.

Thanks,
Pavan.

Hi Pavan,

Compilation of cnxk (both net and event) is also broken on top of the tree with aarch64-linux-gnu-gcc(gcc version 7.5.0 (Linaro GCC 7.5-> 2019.12)).

Below are the error logs which are observed:
