the time the card is inserted and the time that the card is
configured. This can lead to interrupt storms. The O2Micro suggested
workaround is to route the card function interrupt to IRQ1. It
appears from my testing that this is an acceptable workaround for most
chipsets (there's still some issue with the ricoh chipset).
Also, only look at the NOT_A_CARD bit when the bridge tells us there's
a card present. At least one test caused this to be true after the
card was removed, but the author couldn't recreate it with the
workaround in place. The change is more conservative than the
previous code, but still has the work around that wasn't present in
the older code.
BGE_MACSTAT_MI_COMPLETE bit in the MAC status register as a link
change indicator. We turn this bit on now because some of the newer
chips need it, but it usually just means that reading/writing
an MII/GMII register has completed, not that a link change has
occured.
the standard.
1) When the bridge tells us that we have a card that isn't recognized, we
use the force register to force the CV_TEST to run. This test causes the
bridge to re-evaluate the card. Once this re-evaluation process happens,
we get a new interrupt that may say it is ready to process. We try this up
to 20 times. Tests have shown that this appears to correctly reset the
'Unknown card type' problem that I saw on my Sony PCG-505TS.
2) Take a page from OLDCARD and always read the CSC register in the ISR.
Some TI (and it seems maybe Ricoh) chipsets require this to behave
properly. This work around appears to work due to some power management
protocols that were improperly implemented. Maybe it can be removed when
this driver supports the full PME# protocol described in the standards.
3) Minor additional debug printf when debugging is enabled.
4) Minor additional commentary for things that are obvious only after study.
# I'm committing this from my Sony PCG-505TS using shared PCI interrupts
# and NEWCARD, but there are some issues with the Ricoh bridge still, but
# at least now I can boot with the card inserted and have it work.

that the MELCO's id should be 0x18a instead of 0x8a01. Fix this.

is used with VLANs. Since we set the IFCAP_VLAN_MTU flag, we must allow
reception of frames up to 1522 bytes in size rather than 1518.
Note that it is possible to work around this bug by doing:
# ifconfig bge0 mtu 1504
prior to configuring any VLAN interfaces.
