These were getting the macros from an implicit module.h include via device.h, but we are planning to clean that up. Signed-off-by: NPaul Gortmaker <paul.gortmaker@windriver.com> drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.

If the PHY should disappear (for example, on an USB Ethernet MAC), then the driver would leak any undelivered time stamp packets.

Currently the code for VF setup/teardown done by a PF (if_create, mac_add_config, link_status_query etc) is scattered; this patch refactors this code into be_vf_setup() and be_vf_clear(). The if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ is created; so these cmds are now modified to use the MCCQ instead of MBOX.

On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Signed-off-by: NDavid S.

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).
