When I build backports-3.15-rc1-1 I get the following warnings (my linux
kernel version is 3.13.0-24) Mint 17:
Here is my version information:

The reference in iface.c contains:
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,15,0)
static u16 ieee80211_netdev_select_queue(struct net_device *dev,
struct sk_buff *skb,
void *accel_priv,
select_queue_fallback_t fallback)
#elif LINUX_VERSION_CODE >= KERNEL_VERSION(3,13,0)
static u16 ieee80211_netdev_select_queue(struct net_device *dev,
struct sk_buff *skb,
void *accel_priv)
#else
static u16 ieee80211_netdev_select_queue(struct net_device *dev,
struct sk_buff *skb)
#endif
The linux 3.13 net_device_ops structure has the following arguments for
ndo_select_queue:
struct net_device_ops {
int (*ndo_init)(struct net_device *dev);
void (*ndo_uninit)(struct net_device *dev);
int (*ndo_open)(struct net_device *dev);
int (*ndo_stop)(struct net_device *dev);
netdev_tx_t (*ndo_start_xmit) (struct sk_buff *skb,
struct net_device *dev);
u16 (*ndo_select_queue)(struct net_device *dev,
struct sk_buff *skb,
void *accel_priv,
select_queue_fallback_t fallback);
When I modify the ifdefs for the function to include the fallback
argument, iface.c compiles without warnings. I accomplish this by
changing the ifdef:
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,15,0)
to
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,13,0)
and the original select_queue function I modify the ifdef to:
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,15,0)
I also do this for the ieee80211_monitor_select_queue function definiations.
It looks like these conditionals are not aligned properly to the kernel
versions.
Thanks in advance
