net/sfc: fix TSO and checksum offloads for EF10
[ upstream commit be56d20 ] This is workaround for 8000-series EF10 hardware TSO bug. Innermost IP length and outer UDP datagram length must be greater than or equal to the corresponding values derived from the MSS; otherwise, the checksum offloads will break. Fixes: c1ce2ba ("net/sfc: support tunnel TSO on EF10 native Tx datapath") Fixes: 6bc985e ("net/sfc: support TSO in EF10 Tx datapath") Fixes: fec33d5 ("net/sfc: support firmware-assisted TSO") Signed-off-by: Ivan Malov <ivan.malov@oktetlabs.ru> Reviewed-by: Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru> Reviewed-by: Andy Moreton <amoreton@xilinx.com>
