[PATCH net v3 0/2] net: nixge: fix tasklet and DMA teardown

[Myeonghun Pak]

Separate the IRQ/tasklet ordering fix and the DMA shutdown fix from
v2, as requested by Daniel Machon.

Patch 1 releases both IRQ handlers before draining dma_err_tasklet.
Patch 2 masks channel interrupts after recovery has stopped and waits
for DMA reset completion before releasing the buffers. On reset timeout,
it retains those buffers and prevents a later open from replacing them.

Changes in v3:
- Split the IRQ/tasklet ordering fix and DMA shutdown fix into two patches.
- Give each fix its own subject and commit message.
- Order the nixge_stop() local declarations longest to shortest (RXT).

Changes in v2:
- Wait for DMA reset completion; retain buffers and reject reopen on timeout.

v2: https://lore.kernel.org/netdev/20261004042702.1130389-1-mhun512@xxxxxxxxx/
