2020-02-19sfc: remove unused variable 'efx_default_channel_type'YueHaibing
drivers/net/ethernet/sfc/efx.c:116:38: warning: efx_default_channel_type defined but not used [-Wunused-const-variable=] commit 83975485077d ("sfc: move channel alloc/removal code") left behind this, remove it.

2020-02-18sfc: elide assignment of skbEdward Cree
Instead of assigning skb = segments before the loop, just pass segments directly as the first argument to skb_list_walk_safe(). Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-17sfc: move some ARFS code out of headersEdward Cree
efx_filter_rfs_expire() is a work-function, so it being inline makes no sense. It's only ever used in efx_channels.c, so move it there. While we're at it, clean out some related unused cruft. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-17sfc: only schedule asynchronous filter work if neededEdward Cree
Prevent excessive CPU time spent running a workitem with nothing to do. We avoid any races by keeping the same check in efx_filter_rfs_expire().
