When XFRM_ALGO is not enabled, the new igxge ipsec code produces a
link error:
drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa':
ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname'
Simply selectin XFRM_ALGO from here causes circular dependencies, so
to fix it, we probably want this slightly more complex solution that is
similar to what other drivers with XFRM offload do:
A separate Kconfig symbol now controls whether we include the ipsec
offload code. To keep the old behavior, this is left as 'default y'. The
dependency in XFRM_OFFLOAD still causes a circular dependency but is
not actually needed because this symbol is not user visible, so removing
that dependency on top makes it all work.
Fixes: eda0333ac293 ("ixgbe: add VF IPsec management")

You'll probably want to apply these changes to the ixgbevf code as well.

I agree with Shannon's suggested changes. Arnd, are you working on v2?

I was planning to respin it, but didn't get around to it yet, and will
be travelling for the next week, so I'd welcome if you can take over
from here. Shannon's comments all make sense to me as well.

I meant for this to say "default y", as I said in the changelog,
but feel free to pick whichever default makes sense to you
make make the description match ;-)
