2011-10-28stmmac: update normal descriptor structure (v2)Giuseppe CAVALLARO
This patch updates the normal descriptor structure to work fine on new GMAC Synopsys chips. Normal descriptors were designed on the old MAC10/100 databook 1.91 where some bits were reserved: for example the tx checksum insertion and rx checksum offload. The patch maintains the back-compatibility with old MAC devices (tested on STx7109 MAC10/100) and adds new fields that actually new GMAC devices can use. For example, STx7109 (MAC10/100) will pass from the platform tx_coe = 0, enh_desc = 0, has_gmac = 0. A platform like Loongson1B (GMAC) will pass: tx_coe = 1, enh_desc = 0, has_gmac = 1. Thanks to Kelvin, he enhanced the normal descriptors for GMAC (on MIPS Loongson1B platform).

2011-10-19stmmac: limit max_mtu in case of 4KiB and use __netdev_alloc_skb (V2)Giuseppe CAVALLARO
Problem using big mtu around 4096 bytes is you end allocating (4096 +NET_SKB_PAD + NET_IP_ALIGN + sizeof(struct skb_shared_info) bytes -> 8192 bytes : order-1 pages It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD), to have no more than one page per skb. Also the patch changes the netdev_alloc_skb_ip_align() done in init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations allowing the driver to load even in case of memory pressure.

2011-10-19stmmac: add CHAINED descriptor mode support (V4)Giuseppe CAVALLARO
This patch enhances the STMMAC driver to support CHAINED mode of descriptor. STMMAC supports DMA descriptor to operate both in dual buffer(RING) and linked-list(CHAINED) mode. In RING mode (default) each descriptor points to two data buffer pointers whereas in CHAINED mode they point to only one data buffer pointer. In CHAINED mode each descriptor will have pointer to next descriptor in the list, hence creating the explicit chaining in the descriptor itself, whereas such explicit chaining is not possible in RING mode. First version of this work has been done by Rayagond. Then the patch has been reworked avoiding ifdef inside the C code. A new header file has been added to define all the functions needed for managing enhanced and normal descriptors. In fact, these have to be specialized according to the ring/chain usage. Two new C files have been also added to implement the helper routines needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

2011-09-15MII: fix Kconfig dependencies for MIIJeff Kirsher
MII Kconfig option is apart of the core networking drivers and by default NET_CORE is enabled so drivers selecting MII will have MII enabled as well. It was found using the randconfig option during testing, MII would be selected but NET_CORE could be disabled. This caused a dependency error. Resolved the dependency by selecting NET_CORE when MII is selected.

2011-08-27drivers/net/ethernet/*: Enabled vendor Kconfig optionsJeff Kirsher
Based on finds for Stephen Rothwell, where current defconfig's enable a ethernet driver and it is not compiled due to the newly added NET_VENDOR_* component of Kconfig. This patch enables all the "new" Kconfig options so that current defconfig's will continue to compile the expected drivers. In addition, by enabling all the new Kconfig options does not add any un-expected options. CC: Stephen Rothwll <sfc@canb.auug.org.au> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
