Initialised in efx_probe_vf and removal is dealt with in efx_ef10_remove. vf->efx is needed in future patches to change the MAC address of the VF via the parent PF, while the driver is bound to the VF. Example: ip link set dev vf NUM mac LLADDR Signed-off-by: Shradha Shah <sshah@solarflare.com> --- drivers/net/ethernet/sfc/ef10.c | 32 ++++++++++++++++++++++++++++++++ drivers/net/ethernet/sfc/ef10_sriov.c | 3 +++ drivers/net/ethernet/sfc/ef10_sriov.h | 2 ++ 3 files changed, 37 insertions(+) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
