Re: [PATCH net-next 1/1] net: stmmac: enhance XDP ZC driver level switching performance

Hello:

This patch was applied to netdev/net-next.git (master)
by David S. Miller [off-list ref]:

The previous stmmac_xdp_set_prog() implementation uses stmmac_release()
and stmmac_open() which tear down the PHY device and causes undesirable
autonegotiation which causes a delay whenever AFXDP ZC is setup.

This patch introduces two new functions that just sufficiently tear
down DMA descriptors, buffer, NAPI process, and IRQs and reestablish
them accordingly in both stmmac_xdp_release() and stammac_xdp_open().
