sfc: allocate more RX buffers per page Allocating 2 buffers per page is insanely inefficient when MTU is 1500 and PAGE_SIZE is 64K (as it usually is on POWER). Allocate as many as we can fit, and choose the refill batch size at run-time so that we still always use a whole page at once. [bwh: Fix loop condition to allow for compound pages; rebase] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
