Packets with virtio-net headers and ones without virtio-net headers will be provided at the same time so the function can choose the preferred version. In case of e1000e loopback, it prefers to have virtio-net headers as they allows to skip the checksum verification if VIRTIO_NET_HDR_F_DATA_VALID is set.

Not only this is not aligned with the specification, but it also resulted in corrupted IPv6 packets. This is particularly problematic for the igb, a new proposed device implementation; igb provides loopback feature for VMDq and the feature relies on software segmentation. Implement proper TCP segmentation in net_tx_pkt to fix such a scenario.

Even when a packet signals the use of the protocols which these operations can be applied to, the headers for them may not be present because of too short packet or fragmentation, for example. In such a case, the operations cannot be applied safely. Report the presence of headers instead of whether the use of the protocols are indicated with eth_get_protocols(). This also makes corresponding changes to the callers of eth_get_protocols() to match with its new signature and to remove redundant checks for fragmentation.

emulation This change introduces emulation for the Intel 82576 adapter, AKA igb. The details of the device will be provided by the documentation that will follow this change. This initial implementation of igb does not cover the full feature set, but it selectively implements changes necessary to pass tests of Linut Test Project, and Windows HLK. The below is the list of the implemented changes; anything not listed here is not implemented: New features: - igb advanced descriptor handling - Support of 16 queues - SRRCTL.BSIZEPACKET register field - SRRCTL.RDMTS register field - Tx descriptor completion writeback - Extended RA registers - VMDq feature - MRQC "Multiple Receive Queues Enable" register field - DTXSWC.Loopback_en register field - VMOLR.ROMPE register field - VMOLR.AUPE register field - VLVF.VLAN_id register field - VLVF.VI_En register field - VF - Mailbox - Reset - Extended interrupt registers - Default values for IGP01E1000 PHY registers Removed features: - e1000e extended descriptor - e1000e packet split descriptor - Legacy descriptor - PHY register paging - MAC Registers - Legacy interrupt timer registers - Legacy EEPROM registers - PBA/POEM registers - RSRPD register - RFCTL.ACKDIS - RCTL.DTYPE - Copper PHY registers Misc: - VET register format - ICR register format Signed-off-by: Gal Hammer Signed-off-by: Marcel Apfelbaum Signed-off-by: Akihiko Odaki [Jason: don't abort on msi(x)_init()] Signed-off-by: Jason Wang --- hw/net/Kconfig | 5 + hw/net/igb.c | 623 ++++++++ hw/net/igb_common.h | 146 ++ hw/net/igb_core.c | 4077 +++++++++++++++++++++++++++++++++++++++++++++++++++ hw/net/igb_core.h | 146 ++ hw/net/igb_regs.h | 648 ++++++++ hw/net/igbvf.c | 327 +++++ hw/net/meson.build | 2 + hw/net/trace-events | 32 + 9 files changed, 6006 insertions(+) create mode 100644 hw/net/igb.c create mode 100644 hw/net/igb_common.h create mode 100644 hw/net/igb_core.c create mode 100644 hw/net/igb_core.h create mode 100644 hw/net/igb_regs.h create mode 100644 hw/net/igbvf.c (limited to 'hw') diff --git a/hw/net/Kconfig b/hw/net/Kconfig index 1cc1c5775e..18c7851efe 100644 --- a/hw/net/Kconfig +++ b/hw/net/Kconfig @@ -44,6 +44,11 @@ config E1000E_PCI_EXPRESS default y if PCI_DEVICES depends on PCI_EXPRESS && MSI_NONBROKEN +config IGB_PCI_EXPRESS + bool + default y if PCI_DEVICES + depends on PCI_EXPRESS && MSI_NONBROKEN + config RTL8139_PCI bool default y if PCI_DEVICES diff --git a/hw/net/igb.c b/hw/net/igb.c new file mode 100644 index 0000000000..c6d753df87 --- /dev/null +++ b/hw/net/igb.c @@ -0,0 +1,623 @@ +/* + * QEMU Intel 82576 SR/IOV Ethernet Controller Emulation + * + * Datasheet: + * https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/82576eg-gbe-datasheet.pdf + * + * Copyright (c) 2020-2023 Red Hat, Inc. + * Copyright (c) 2015 Ravello Systems LTD (http://ravellosystems.com) + * Developed by Daynix Computing LTD (http://www.daynix.com) + * + * Authors: + * Akihiko Odaki + * Gal Hammmer + * Marcel Apfelbaum + * Dmitry Fleytman + * Leonid Bloch + * Yan Vugenfirer + * + * Based on work done by: + * Nir Peleg, Tutis Systems Ltd. for Qumranet Inc. + * Copyright (c) 2008 Qumranet + * Based on work done by: + * Copyright (c) 2007 Dan Aloni + * Copyright (c) 2004 Antony T Curtis + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
