* Merge if_em.c:1.82 from HEAD to RELENG_6:Robert Watson2005-11-141-10/+14
| | | | | | | | | | | | 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. Notes: svn path=/stable/6/; revision=152408

| | | | | | | | | | | | | | | | | | | | | | | - rev. 1.76. Removed FreeBSD 4.x code. - rev. 1.77, 1.79. Together with rev. 1.71 (already merged) this fixes problems when some code is executed in driver when em_process_receive_interrupts() drops lock. This can occur at runtime, when polling(4) mode is changed to interrupt driver or vise versa, but more likely this can happen when administrator issues some ifconfig commands. - rev. 1.78. In em_process_receive_interrupts(), call bus_dmamap_sync() for the descriptors set each time we modify one descriptor, instead of doing it only at the function exit. - rev. 1.80. Loop in em_intr() until interrupt cause register is clear, don't mask overrun interrupt. - rev. 1.81. Several locking and other fixes. See particular revision logs for more detailed information.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-24/+24
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | the interface when going to toggle VLAN support for internal reasons. If the IFCAP_VLAN_HWTAGGING bit is cleared, we should rely on the (re)init routine to turn VLAN support off and never touch the relevant hardware bits. This applies to other capability bits, too. The user obviously has a reason for clearing a capability bit, e.g., if his particular NIC is buggy and hangs if a certain hardware capability is turned on even for a fraction of a second. The flag adapter->em_insert_vlan_header still is set or reset irrespective of the IFCAP_VLAN_HWTAGGING setting, as before, in order to handle the case when a user sets promiscuous mode on an interface first and later turns its IFCAP_VLAN_HWTAGGING bit on. This change might look orthogonal to rev#1.85, but in fact it is not. It introduces bugfixes that hopefully will make implementing the general scheme mentioned in the commit message of rev#1.85 easier. Notes: svn path=/head/; revision=140859

* Correct a bug in the if_em driver relating to the use of vlans withRobert Watson2004-11-122-6/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | promiscuous mode introduced in 1.45, which programs the em card not to strip or prepend tags when in promiscuous mode without also modifying behavior to manually prepend a vlan header in the event that the card isn't doing it on transmit. Due to a feature of card operation, if the global VLAN prepend/strip register isn't set, setting the VLAN tag flag on individual packet descriptors will cause the packet to be transmitted using ISL encapsulation rather than 802.1Q VLAN encapsulation. This fix causes em_encap() to prepend the header by tracking whether the card is configured to temporarily disable prepending/stripping due to promiscuous mode. As a result, entering promiscuous mode on the parent em interface no longer causes vlans to appear to "wedge" or transmit ISL-encapsulated frames, which typically will not be configured/spoken by the other endpoints on the VLAN trunk. This bug may also exist in other drivers, and the additional vlan encapsulation logic should be abstracted and centralized in if_vlan.c if so. RELENG_5_3 candidate.

* Use an alignment of 1 instead of PAGE_SIZE for the rx and tx buffer tags.Scott Long2004-10-191-12/+2
| | | | | | | | | | | | | Since the e1000 DMA engines hava no constraints on the alignment of buffer transfers, there is no reason to tell busdma that there is. This save a minimum of 1 malloc call per packet, which translates to eliminating 4 locks. It also means that buffers are not needlessly bounced when transfered. The end result is a 38% improvement in pps in a 4 way bridging environment. Obtained from: Sandvine, Inc. Notes: svn path=/head/; revision=136685
