      netpoll: revert 6bdb7fe3 and fix be_poll() instead · 072a9c48
      Amerigo Wang authored
      Against -net.
      In the patch "netpoll: re-enable irq in poll_napi()", I tried to
      fix the following warning:

      by reenabling IRQ before calling ->poll, but it seems more
      problems are introduced after that patch:
      So it is safe to fix be2net driver code directly.
      This patch reverts the offending commit and fixes be_poll() by
      avoid disabling BH there, this is okay because be_poll()
      can be called either by poll_napi() which already disables
      IRQ, or by net_rx_action() which already disables BH.

      brcm80211: smac: set interface down on reset · ea2d2183
      Vladimir Zapolskiy authored
      This change marks interface as down on reset, otherwise the driver can't
      reinitialize itself properly.
      Without the change a transient problem turns out to be critical and leads
      to inavailability to reset the driver without brcmsmac module unload/load
