When the PCI adapter is going through error recovery, a call to mlx4_ib_post_send() will return success without the command actually arriving to the hardware. Adding a call to pci_channel_offline() to check the state of the PCI slot and returning an error will allow the upper layers to be aware that the command didn't succeed.
Is putting this call in fast path common practice in other (e.g Ethernet) drivers?
