I've disabled both rxcsum and txcsum, and that solved a problem. Judging from that this helped Andrzej with sk(4) and me with ale(4) driver, that's not a single driver problem. Does his mean that we have global problems with checksum offloading? -- Dmitry Marakasov . 55B5 0596 FF1E 8D84 5F56 9510 D35A 80DD F9D2 F77D amdmi3@amdmi3.ru ..: jabber: amdmi3@jabber.ru http://www.amdmi3.ru
