Impose a large RX private data area only when the A050385 erratum is present on the hardware. A smaller buffer size is sufficient in all other scenarios. This enables a wider range of linear frame sizes in non-erratum scenarios Fixes: 3c68b8fffb48 ("dpaa_eth: FMan erratum A050385 workaround") Signed-off-by: Camelia Groza <camelia.groza@nxp.com> --- drivers/net/ethernet/freescale/dpaa/dpaa_eth.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
