2014-07-23ethernet: realtek: use pci_device_idVarka Bhadram
This patch use the struct pci_device_id instead of using macro DEFINE_PCI_DEVICE_TABLE which is deprecated and should not be used. And also moves these ids after probe and remove functionalities. Signed-off-by: Varka Bhadram <varkab@cdac.in> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-23ethernet: realtek: use module_pci_driverVarka Bhadram
This patch converts to use the macro module_pci_driver, which makes the code smaller and simpler. Previously in this driver we are having driver version info will be printed log buffer based on whether the driver selected as module or statically into image itself. By using the module_pci_driver that part of the code removed. For the first time of the device init, we are making the version info to be printed once.

2014-03-138139cp: Don't receive packets when the napi budget == 0Eric W. Biederman
Processing any incoming packets with a with a napi budget of 0 is incorrect driver behavior. This matters as netpoll will shortly call drivers with a budget of 0 to avoid receive packet processing happening in hard irq context. Signed-off-by: "Eric W.

2012-12-038139cp: properly support change of MTU values [v2]John Greene
The 8139cp driver has a change_mtu function that has not been enabled since the dawn of the git repository. However, the generic eth_change_mtu is not used in its place, so that invalid MTU values can be set on the interface. Original patch salvages the broken code for the single case of setting the MTU while the interface is down, which is safe and also includes the range check. Now enhanced to support up or down interface. v2: fix case where rxbufsz isn't changed in the up state case Original patch from http://lkml.indiana.edu/hypermail/linux/kernel/1202.2/00770.html Testing: has been test on virtual 8139cp setup without issue, have no access real hardware 8139cp, need testing help.

2012-11-258139cp: set ring address after enabling C+ modeDavid Woodhouse
This fixes (for me) a regression introduced by commit b01af457 ("8139cp: set ring address before enabling receiver"). That commit configured the descriptor ring addresses earlier in the initialisation sequence, in order to avoid the possibility of triggering stray DMA before the correct address had been set up. Unfortunately, it seems that the hardware will scribble garbage into the TxRingAddr registers when we enable "plus mode" Tx in the CpCmd register. Observed on a Traverse Geos router board. To deal with this, while not reintroducing the problem which led to the original commit, we augment cp_start_hw() to write to the CpCmd register *first*, then set the descriptor ring addresses, and then finally to enable Rx and Tx in the original 8139 Cmd register. The datasheet actually indicates that we should enable Tx/Rx in the Cmd register *before* configuring the descriptor addresses, but that would appear to re-introduce the problem that the offending commit b01af457 was trying to solve. And this variant appears to work fine on real hardware. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Cc: stable@kernel.org [3.5+] Signed-off-by: David S. Miller <davem@davemloft.net>

2012-10-08net: gro: selective flush of packetsEric Dumazet
Current GRO can hold packets in gro_list for almost unlimited time, in case napi->poll() handler consumes its budget over and over. In this case, napi_complete()/napi_gro_flush() are not called. Another problem is that gro_list is flushed in non friendly way : We scan the list and complete packets in the reverse order. (youngest packets first, oldest packets last) This defeats priorities that sender could have cooked. Since GRO currently only store TCP packets, we dont really notice the bug because of retransmits, but this behavior can add unexpected latencies, particularly on mice flows clamped by elephant flows. This patch makes sure no packet can stay more than 1 ms in queue, and only in stress situations. It also complete packets in the right order to minimize latencies.

Currently, we terminate the eeprom access through clearing the CS by: RTL_W8 (Cfg9346, ~EE_CS); or writeb (~EE_CS, ee_addr); This would left the eeprom into "Config. Register Write Enable:" state which is not expcted as the highest two bits were set to 0x11 ( expected is the "Normal" mode (0x00)).

2012-01-038139cp: properly config rx mode after resumingJason Wang
Rx mode should be reset after resming, so unconditionally updating rx mode rather than conditionally updating based on the value we remembered, otherwise unexpected value may be used by the nic after resuming. btw. I find and test this when debugging guest hibernation in qemu, as I did not have a 8139cp card in hand, this patch is untested in a physical 8139cp card, plase review it carefully.

Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
