Description Jiri Olsa 2010-01-15 09:42:47 UTC 
Description of problem:

missing symbols in white list:

vlan_gro_frags
napi_get_frags
napi_gro_flush
napi_gro_frags
Comment 1 Gary Smith 2010-03-19 15:39:38 UTC 
Fujitsu are requesting that these symbols also be added to the 5.6 whitelist please:

pci_disable_sriov
pci_enable_sriov
Comment 2 Larry Troan 2010-08-03 21:38:03 UTC 
Requesting BLOCKER or reason these won;t be in 5.6.
Comment 3 Jon Masters 2010-08-24 04:45:34 UTC 
Can you please let me know which modules these are for? I suspect the answer to adding NAPI to the whitelist is "no", but I will check.
Comment 4 Martin Wilck 2010-08-24 08:28:26 UTC 
Jon,

napi_gro_flush() is required by most current OEM LAN drivers (igb, ixgbe, bnx2). Without it, no fully-deatured LAN driver can be provided via DUP. Drives need to define a dummy replacement function instead, which makes me feel very uncomfortable.

Note that napi_gro_receive() is already part of the 5.5 KABI (bug #526342), so why not napi_gro_flush()?

pci_disable_sriov
pci_enable_sriov

Without these, no DUP-provided driver can offer SR-IOV functionality. That is going to be a significant restriction as soon as customers start using SR-IOV. When a bug fix requires a DUP driver (from Red Hat or a partner, doesn't matter), SR-IOV functionality is not available any more.

Thanks for the reply Martin. I'll include it in the processing of this request.
Comment 6 Larry Troan 2010-09-02 20:54:58 UTC 
Have a devel ACK. Can I get a QA ACK please. Fujitsu will test this.
