ieee80211.h for user space regulatory daemon Attached are two small patches for include/net/ieee80211.h to prepare for later submission of code to implement a user-space daemon that supplies 802.11 regulatory information. The first change adds a bit indicating that 802.11h rules are to be applied to a channel. As discussed earlier in this list, a single bit is unlikely to be sufficient; however, at this time I have been unable to find any regulations implementing differences between 802.11a and 802.11h other than DFS, radar detection and passive scanning. A single bit is thus sufficient to convey to the driver that these rules should be obeyed. The second change adds comments to the freq and max_power fields of struct ieee80211_channel to indicate the units that are used. Signed-Off-By: Larry Finger Signed-off-by: John W.

It appears that this is an unintended consequence of relinquinshing the queue lock while transmitting. That in turn is needed for devices that spend a lot of time in their transmit routine. There are no advantages to be had as devices with queues are inherently single-threaded (the loopback device is not but then it doesn't have a queue). Even if you were to add a queue to a parallel virtual device (e.g., bolt a tbf filter in front of an ipip tunnel device), you would still want to process the queue in sequence to ensure that the packets are ordered correctly. The solution here is to steal a bit from net_device to prevent this. BTW, as qdisc_restart is no longer used by anyone as a module inside the kernel (IIRC it used to with netif_wake_queue), I have not exported the new __qdisc_run function.

So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu Signed-off-by: David S.
