[PATCH] kvm: qemu: Drop the mutex while reading from tapfd

From: Mark McLoughlin <[EMAIL PROTECTED]> The idea here is that with GSO, packets are much larger and we can allow the vcpu threads to e.g. process irq acks during the window where we're reading these packets from the tapfd. One known issue with this is that it triggers a subtle SMP race in the k

[PATCH] kvm: qemu: Add support for partial csums and GSO

From: Mark McLoughlin <[EMAIL PROTECTED]> The tun/tap driver in 2.6.27 contains a new IFF_VNET_HDR flag which makes every packet read from or written to the tap fd be preceded by a virtio_net_hdr header. This allows us to pass larger packets and packets with partial checkums between the guest and
