[dpdk-dev] [PATCH v2 1/4] net/bnx2x: do not cast function pointers as a policy

[Andy Green]

This is stopping the compiler telling you when you have
done something stupid... that is something none of us
can afford...

Now gcc 8.x can tell you did something stupid despite
trying to hide the evidence.

Remove all the "black magic" casts.

Fix the actual problems.

[dpdk-dev] [PATCH v3 1/4] net/bnx2x: do not cast function pointers as a policy

[Andy Green]

This is stopping the compiler telling you when you have
done something stupid... that is something none of us
can afford...

Now gcc 8.x can tell you did something stupid despite
trying to hide the evidence.

Remove all the "black magic" casts.

Fix the actual problems.

[dpdk-dev] [PATCH v3 2/4] net/bnx2x: correct unmeetable comparison

[Andy Green]

/home/agreen/projects/dpdk/drivers/net/bnx2x/elink.c:
In function ‘elink_check_kr2_wa’:
/home/agreen/projects/dpdk/drivers/net/bnx2x/elink.c:12922:28:
error: bitwise comparison always evaluates to false
[-Werror=tautological-compare]
        ((next_page & 0xe0) == 0x2))));

This was fixed elsewhere in 2014

To be able to apply this fix in dpdk I think we need maintainers ack on this
change, they are cc'ed.
