Note that with these changes, these drivers now depend on locking the global if_addr_mtx, so binary modules of these drivers will not work on 5.4 or earlier releases. Approved by: rwatson (mentor)

The receive function em_process_receive_interrupts() unlocks the adapter while ether_input() processes the packet, and then locks it back. In the meantime, em_init() may be called, either from em_watchdog() from softclock interrupt or from the ifconfig(8) program. The em_init() resets the card, in particular it sets adapter->next_rx_desc_to_check to 0 and resets hardware RX Head and Tail descriptor pointers. The loop in em_process_receive_interrupts() does not expect these things to change, and a mess may result. PR: kern/87418 Submitted by: Dmitrij Tejblum

Put probe-time printf of adapter speed and duplex behind bootverbose: since the link takes a bit to negotiate, the information is pretty much never available during the probe. As such, the boot output pretty much always prints N/A for speed and duplex. Since we print out the output of ifconfig during the user space boot, this early boot information is also generally redundant, and added to the noise.

Run em_local_timer() once per second instead of running it once per 2 seconds. This makes gathering of error stats more precise, and netstat(1) output look right. Reviewed by: tackerman

Since em(4) is very popular and does not use miibus(4) add special hack

- Always respect IFCAP_VLAN_HWTAGGING. - By default, disable VLAN processing in hardware since we are not ready yet to handle all aspects of using it together with promiscuous mode. Agreed with: rwatson
