| | | | | | | | - update interface baud rate properly so userland programs such as a SNMP daemon or bgpctl/ospfctl for example will display the correct interface speed instead of always saying 1 Gbps. From FreeBSD

* remove a bit of unused code.brad2005-12-101-4/+1
| | | | | Pointed out by Andrey Matveev <evol at online dot ptt dot ru> through noticing a missing splx which pointed out the fact that code is unused to me.

* fix wrong htole usage in the 82544 PCI-X workaround codepath in em_encap().brad2005-11-181-7/+4
| | | | From FreeBSD
* revert part of rev 1.45 ..brad2005-11-181-14/+4
| | | | | | | | | - Modify the caller of em_encap() to detect a NULL m_head and not try to queue the mbuf if that happens. which was in preparation for a software-based workaround for a HW VLAN tagging issue, but due to a HW limitation with tagging, we cannot use HW VLAN tagging at all.
* remove braces and fix indenting here so its easier to read.brad2005-11-151-4/+3

* - Introduce two more stat counters, counting number of RXbrad2005-11-131-21/+27
| | | | | | | | | | | | | overruns and number of watchdog timeouts. - Do not increase if->if_oerrors in em_watchdog(), since this leads to counter slipping back, when if->if_oerrors is recalculated in em_update_stats_counters(). Instead increase watchdog counter in em_watchdog() and take it into account in em_update_stats_counters(). From glebius FreeBSD ok dlg@

* While in em_process_receive_interrupts() processing the packet em_init()brad2005-10-161-15/+21
| | | | | | | | | | | | may be called (either from em_watchdog() from softclock interrupt or from ifconfig). em_init() resets the card, in particular it sets sc->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. >From glebius FreeBSD ok krw@
