This series adds support for virtio network notification
coalescing (VIRTIO_NET_F_NOFT_COAL) in virtio-net.
Patch 1: Introduces a Tx dispatch helper to unify tx path
handling.
Patch 2: Implements notification coalescing support and feature
negotiation for virtio-net.
Koushik Dutta (2):
Introduce virtio_net_handle_tx_dispatch() to unify TX path handling.
This dispatcher dynamically selects between timer-based and BH-based
TX processing based on configuration.
Implement VirtIO Network Notification Coalescing
(VIRTIO_NET_F_NOTF_COAL). This allows guests to reduce interrupt
overhead by configuring coalescing parameters via ethtool -C for
both RX and TX paths.
