* net: ethernet: Remove superfluous ether_setup after alloc_etherdevTobias Klauser2014-10-03
| | | | | | | | | | | | | | There is no need to call ether_setup after alloc_ethdev since it was already called there. Follow commits c706471b2601 ("net: axienet: remove unnecessary ether_setup after alloc_etherdev") and 3c87dcbfb36c ("net: ll_temac: Remove unnecessary ether_setup after alloc_etherdev") and fix the pattern in all remaining ethernet drivers.

* net: calxedaxgmac: Fix panic caused by MTU change of active interfaceAndreas Herrmann2013-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changing MTU size of an xgmac network interface while it is active can cause a panic like skbuff: skb_over_panic: text:c03bc62c len:1090 put:1090 head:edfb6900 data:edfb6942 tail:0xedfb6d84 end:0xedfb6bc0 dev:eth0 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:126! Internal error: Oops - BUG: 0 [#1] SMP ARM Modules linked in: CPU: 0 PID: 762 Comm: python Tainted: G W 3.10.0-00015-g3e33cd7 #309 task: edcfe000 ti: ed67e000 task.ti: ed67e000 PC is at skb_panic+0x64/0x70 LR is at wake_up_klogd+0x5c/0x68 This happens because xgmac_change_mtu modifies dev->mtu before the network interface is quiesced. And thus there still might be buffers in use which have a buffer size based on the old MTU. To fix this I moved the change of dev->mtu after the call to xgmac_stop. Another modification is required (in xgmac_stop) to ensure that xgmac_xmit is really not called anymore (xgmac_tx_complete might wake up the queue again). I've tested the fix by switching MTU size every second between 600 and 1500 while network traffic was going on. The test box survived a test of several hours (until I've stopped it) whereas w/o this fix above panic occurs after several minutes (at most). Change since v1: - remove call to netif_stop_queue at beginning of xgmac_stop - use netif_tx_disable instead of locking+netif_stop_queue Signed-off-by: Andreas Herrmann <andreas.herrmann@calxeda.com> Signed-off-by: David S.

* net: calxedaxgmac: determine number of address filters at runtimeRob Herring2013-10-02
| | | | | | | | | | | Highbank and Midway xgmac h/w have different number of MAC address filter registers with 7 and 31, respectively. Highbank has been wrong, so fix it and detect the number of filter registers at run-time. Unfortunately, the version register is the same on both SOCs, so simply test if write to the last filter register will take a value. It always reads as 0 if not.

| | | | | | | | | | | | | | | | | | | | | | | | | Fix xgmac_set_rx_mode to handle several conditions that were not handled correctly as Lennert Buytenhek describes: If we have, say, 100 unicast addresses, and 5 multicast addresses, the unicast address count check will evaluate to true, and set use_hash to true. The multicast address check will however evaluate to false, and use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true from the unicast check, netdev_for_each_mc_addr() will program the multicast addresses into the hash table instead of using the MAC address registers, but since the HMC bit wasn't set, the hash table won't be checked for multicast addresses on receive, and we'll stop receiving multicast packets entirely. Also, there is no code that zeroes out MAC address registers reg..31 at the end of this function, meaning that under the right conditions, unicast/multicast addresses that were previously in the filter but were then deleted won't be cleared out.

* net: calxedaxgmac: fix race with tx queue stop/wakeRob Herring2013-09-03
| | | | | | | | | | | | | | | | Since the xgmac transmit start and completion work locklessly, it is possible for xgmac_xmit to stop the tx queue after the xgmac_tx_complete has run resulting in the tx queue never being woken up. Fix this by ensuring that ring buffer index updates are visible and recheck the ring space after stopping the queue. Also fix an off-by-one bug where we need to stop the queue when the ring buffer space is equal to MAX_SKB_FRAGS. The implementation used here was copied from drivers/net/ethernet/broadcom/tg3.c.

* net: calxedaxgmac: fix possible skb free before tx completeRob Herring2013-09-03
| | | | | | | | | | | | | | | The TX completion code may have freed an skb before the entire sg list was transmitted. The DMA unmap calls for the fragments could also get skipped. Now set the skb pointer on every entry in the ring, not just the head of the sg list. We then use the FS (first segment) bit in the descriptors to determine skb head vs. fragment. This also fixes similar bug in xgmac_free_tx_skbufs where clean-up of a sg list that wraps at the end of the ring buffer would not get unmapped.

Last identified bug is that fat skbs can be recycled and it can endup using high order pages after few iterations. With help from Maxime Bizon, who pointed out that commit 87151b8689d (net: allow pskb_expand_head() to get maximum tailroom) introduced this regression for recycled skbs.
