Finally, return the error status. base-commit: 1806da76cb81088ea026ca3441551782b850e393 Fea.Wang (4): hw/dma: Enhance error handling in loading description hw/dma: Break the loop when loading descriptions fails hw/dma: Add a trace log for a description loading failure hw/net: Fix the transmission return size hw/dma/trace-events | 3 +++ hw/dma/xilinx_axidma.c | 27 +++++++++++++++++++++++---- hw/net/xilinx_axienet.c | 2 +- 3 files changed, 27 insertions(+), 5 deletions(-) -- 2.34.1
