This commit fix current QU bit implementation that may be used in mDNS
protocol. Indeed, until now, if a packet with QU bit set is received,
it is decoded as:
{
...
questions: [
{
name: '...',
type: 'PTR',
class: 'UNKNOWN_32769'
},
{
name: '...',
type: 'PTR',
class: 'UNKNOWN_32769'
}
],
...
}
Instead of :
{
...
questions: [
{
name: '...',
type: 'PTR',
class: 'IN'
},
{
name: '...',
type: 'PTR',
class: 'IN'
}
],
...
}
This commit adds a proper QU bit support via the qu_bit field.
It enables:
- The encoder to parse properly both the class and the QU bit
- THe decoder to encode a DNS packet with the QU bit set
