[PATCH] ixgbe: eliminate duplicate filterlist symbols

[PATCH] ixgbe: eliminate duplicate filterlist symbols

[David Harton]

Some compilers generate warnings for duplicate symbols for the
set of filter lists current defined in ixgbe_ethdev.h.
This commits moves the defintion and declaration to the source
file that actually uses them and provides a function to
initialize the values akin to its flush function.

Will it work if list initialization converted to the static
initialization? That would remove requirement of this function call.

I was trying to keep the behavior the same:
  .probe -> eth_ixgbe_dev_init -> ixgbe_filterlist_init
  .remove -> eth_ixgbe_dev_uninit -> ixgbe_filterlist_flush

While I think the below would work I always like mirror/parallel relationships like ctor/dtor for objects.

Is that reasonable?

Thanks,
Dave

I would agree if ixgbe_filterlist_init() initializes something more than
list itself, but for this case initialization can be avoided completely
which I would prefer.

Driver maintainer also cc'ed for more comment.

It seems there is no more comment. So, I suggest lets focus on your fix,
my suggestion to convert to static initialization can be done later if
desired.

Still, what do you think about moving declaration of structs as well to
the ixgbe_flow.c? After your change, only ixgbe_flow.c will be using
them, no need to keep them in ixgbe_ethdev.h.

Thanks,

Works for me.  Let me make the changes and test.

[PATCH v2] ixgbe: eliminate duplicate filterlist symbols

[David C Harton]

From: David Harton <dharton@cisco.com>

Some compilers generate warnings for duplicate symbols for the
set of filter lists current defined in ixgbe_ethdev.h.
This commits moves the defintion and declaration to the source
file that actually uses them and provides a function to
initialize the values akin to its flush function.
