[-- Attachment #1 --] Hi, when receiving packets via netmap (current GitHub version) on a Chelsio T6 vcc0 device on -CURRENT, it appears that the Ethernet header starts at an offset of two bytes into the netmap slot. So far, I have only used netmap with various Intel NICs, where the Ethernet header starts at offset zero. Is this a bug? Is this to be expected? Thanks, Lars [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEmpq0ZpSoejRmyhheVLXDCb9wwVcFAls+NKwACgkQVLXDCb9w wVd3xg//dp+xCSpr4G3kcOrD9KzruB+C4Il9gsKa2SKsCLe154JUUo1ZDloh08+j RxRgJEE5eVfV2s+lhtLa85JnegKond5s/Q3bsNbHueYH7TMTrKOrU/3uW+CqgcFA YA9wyZU6onFMrZiXk2VsRNPErn2E4gt7rJ03EyrKvg+MTzaTI+eLZV+zPxnFbuqa Z2RV/tO336zRJhgWjeMg8j5rDvD5mUJ8WuqJtxZdle24D4MSfDZZ16ILS5YbxFvF P21+ISTTOMeWqfBlCBBeVLWLKRw4Vk0C3qxNKZxEvGhwyYApFniQP0FpCnIRxfCN HCYcr1me/5EnI3Zy6hoJ8EhWkkyaH7DkKt8+gcUZgTbCQOFIuMdIHYM5Pqv8R683 dcCRjpuTldZlqS1zvm4gbQDezhrBHw72GsseIdQPLwZvO4kc+UG5kkbhD/E+BjIQ 31x37U2/RuqeMmHW6j/b9w6g66E95KABj3q3GP0mXme/QzsaECzLaIPMHJVWAHyL VFqTZwwkPvGA5pfyDsf557FqHVbclfKIY3ktZd0SgXJc+637cI1iSs2n03I0/EJR xSTgQVWrU4UgFgiehjP2WOy/kAotFMkvGycJB/kEYn7E9TLlzeyVbrra5jps9vPd G5SmIdvaeHh6MRhYri9+WiTCKwr4a9yuk5I6sstYBk/F7iQ0Zyc= =ys76 -----END PGP SIGNATURE-----
