[PATCH RFC 1/2] virtio: support for urgent descriptors
Below should be useful for some experiments Jason is doing.
I thought I'd send it out for early review/feedback.
Compiled-only at this point.
event idx feature allows us to defer interrupts until
a specific # of descriptors were used.
Sometimes it might be useful to get an interrupt after
a specific descriptor, regardless.
This adds a descriptor flag for this, and an API

[PATCH net-next RFC 0/3] virtio-net: Conditionally enable tx interrupt
Hello all:
We free old transmitted packets in ndo_start_xmit() currently, so any
packet must be orphaned also there. This was used to reduce the overhead of
tx interrupt to achieve better performance. But this may not work for some
protocols such as TCP stream. TCP depends on the value of sk_wmem_alloc to
implement various optimization for small packets stream such as TCP small
queue and auto
