- Don't disable interrupt in bge_intr(), just acknowledge it. This avoids
potential lose of interrupt when interrupt gets re-enabled, since writing
to BGE_MBX_IRQ0_LO also serves as interrupt acknowledgment.
- Move interrupt acknowledgment before reading status block. This lets us
read the correct/complete status block.
- Reset ifnet.if_timer, only if there is nothing pending to be TXed.
