  In case of link speed set to 1Gb at peer side (with autoneg or with
defined speed) and cable not plugged-in when device is configured
and started, then link status is not updated properly with new speed
as no link setup is triggered.

To avoid this issue, IXGBE_FLAG_NEED_LINK_CONFIG is set to try a link
setup each time link_update() is triggered and current link status is
down. When cable is plugged-in, link setup will be performed via
ixgbe_setup_link().

This patch is dying: more than 2 months without any review!

A tip to help ixgbe maintainers in their task, please check this regularly:

Now there is following macro in DPDK 17.02-rc2.
#define IXGBE_FLAG_MACSEC           (uint32_t)(1 << 3)
You can redefine it as #define IXGBE_FLAG_NEED_LINK_CONFIG (uint32_t)(1 << 4)

Thanks, I'll send a v2.

Do you agree with the rest of the patch?
