The fix is to introduce new network helper and check the queue->delivering. Thanks Changes since V2: - add more fixes from Alexander Changes since V1: - Fix dp8393x compiling - Add rtl8139 fix - Tweak the commit log - Silent patchew warning Alexander Bulekov (4): rtl8139: switch to use qemu_receive_packet() for loopback pcnet: switch to use qemu_receive_packet() for loopback cadence_gem: switch to use qemu_receive_packet() for loopback lan9118: switch to use qemu_receive_packet() for loopback Jason Wang (6): net: introduce qemu_receive_packet() e1000: switch to use qemu_receive_packet() for loopback dp8393x: switch to use qemu_receive_packet() for loopback packet msf2-mac: switch to use qemu_receive_packet() for loopback sungem: switch to use qemu_receive_packet() for loopback tx_pkt: switch to use qemu_receive_packet_iov() for loopback hw/net/cadence_gem.c | 2 +- hw/net/dp8393x.c | 2 +- hw/net/e1000.c | 2 +- hw/net/lan9118.c | 2 +- hw/net/msf2-emac.c | 2 +- hw/net/net_tx_pkt.c | 2 +- hw/net/pcnet.c | 2 +- hw/net/rtl8139.c | 2 +- hw/net/sungem.c | 2 +- include/net/net.h | 5 +++++ include/net/queue.h | 8 ++++++++ net/net.c | 38 +++++++++++++++++++++++++++++++------- net/queue.c | 22 ++++++++++++++++++++++ 13 files changed, 75 insertions(+), 16 deletions(-) -- 2.24.3 (Apple Git-128)
