Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the
structure or union members.
GCC Manual:
"Specifying Attributes of Types
packed
This attribute, attached to struct or union type definition, specifies
that
each member of the structure or union is placed to minimize the memory
required. When attached to an enum definition, it indicates that the
smallest integral type should be used.
Specifying this attribute for struct and union types is equivalent to
specifying the packed attribute on each of the structure or union
members."

* DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are
|
|
* created for each DLCI associated with a FRAD. The FRAD driver
|
|
* is not truly a network device, but the lower level device
|
|
* handler. This allows other FRAD manufacturers to use the DLCI
|
|
* code, including its RFC1490 encapsulation alongside the current
|
|
* implementation for the Sangoma cards.
|
|
*
|
|
* Version: @(#)if_ifrad.h 0.15 31 Mar 96
|
|
*
|
|
* Author: Mike McLagan <mike.mclagan@linux.org>
|
|
*
|
|
* Changes:
|
|
* 0.15 Mike McLagan changed structure defs (packed)
|
|
* re-arranged flags
|
|
* added DLCI_RET vars
