_NET_RX_FRAGMENT_BUFFER_ALLOCATION_MODE enumeration

Description

The NET_RX_FRAGMENT_BUFFER_ALLOCATION_MODE enumeration identifies how the operating system should allocate NET_FRAGMENT receive buffers for a net adapter client driver's receive queues.

Constants

`NetRxFragmentBufferAllocationModeSystem:0`

The operating system allocates NET_FRAGMENT receive buffers on behalf of the client driver.

`NetRxFragmentBufferAllocationModeDriver:1`

The operating system never allocates NET_FRAGMENT receive buffers. The client driver is responsible for buffer allocation.

Remarks

This enumeration is a value of the NET_ADAPTER_RX_CAPABILITIES structure. Together with NET_RX_FRAGMENT_BUFFER_ATTACHMENT_MODE, it specifies how a net adapter client driver would like to configure its receive queue fragment buffers. For more information, see NET_ADAPTER_RX_CAPABILITIES.
