Revert "[netdrvr e100] experiment with doing RX in a similar manner to eepro100"

2007-06-12T22:52:31+00:00

This reverts commit d52df4a35af569071fda3f4eb08e47cc7023f094. This patch attempted to fix e100 for non-cache coherent memory architectures by using the cb style code that eepro100 had and using the EL and s bits from the RFD list. Unfortunately the hardware doesn't work exactly like this and therefore this patch actually breaks e100. Reverting the change brings it back to the previously known good state for 2.6.22. The pending rewrite in progress to this code can then be safely merged later. Signed-off-by: Auke Kok Signed-off-by: Jeff Garzik

e100: Optionally use I/O mode only to access register space

2007-04-28T15:01:07+00:00

It appears that some systems still like e100 better if it uses I/O access mode. Setting the new parameter use_io=1 will cause all driver instances to use io mapping to access the register space on the e100 device. Signed-off-by: Jesse Brandeburg Signed-off-by: Auke Kok Signed-off-by: Jeff Garzik

e100: allow bad MAC address when running with invalid eeprom csum

2007-04-28T15:01:07+00:00

Seved Torstendahl suggested to let the module parameter for invalid eeprom checksum control the valid mac address test. If this bypass happens we should print a different message, or at least one that is correct, maybe something like below Signed-off-by: Jesse Brandeburg Signed-off-by: Auke Kok Signed-off-by: Jeff Garzik

[netdrvr e100] experiment with doing RX in a similar manner to eepro100

2007-04-28T15:01:05+00:00

I was going to say that eepro100's speedo_rx_link() does the same DMA abuse as e100, but then I noticed one little detail: eepro100 sets both EL (end of list) and S (suspend) bits in the RFD as it chains it to the RFD list. e100 was only setting the EL bit. Hmmm, that's interesting. That means that if HW reads a RFD with the S-bit set, it'll process that RFD and then suspend the receive unit. The receive unit will resume when SW clears the S-bit. There is no need for SW to restart the receive unit. Which means a lot of the receive unit state tracking code in the driver goes away. So here's a patch against 2.6.14. (Sorry for inlining it; the mailer I'm using now will mess with the word wrap). I can't test this on XScale (unless someone has an e100 module for Gumstix :) . It should be doing exactly what eepro100 does with RFDs. I don't believe this change will introduce a performance hit because the S-bit and EL-bit go hand-in-hand meaning if we're going to suspend because of the S- bit, we're on the last resource anyway, so we'll have to wait for SW to replenish.

[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}

2007-04-26T05:28:29+00:00

To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo

e100: fix napi ifdefs removing needed code

2007-02-02T13:34:10+00:00

e100: fix napi ifdefs removing needed code From: Auke Kok The e100 driver is NAPI mode only. We need to netif_poll_disable during suspend and shutdown. The non-NAPI driver code was removed and is only avaiable in the out-of-tree e100 kernel driver. Signed-off-by: Auke Kok Signed-off-by: Jeff Garzik
