t4_ofld_eq_free(9)
π t4_ofld_eq_free β the manual page, but make it make sense
ok so real talk: this is a Kernel API Manual page for t4_ofld_eq_free(9), and it's genuinely one of the most slay little functions in the cxgb4 universe. it frees an offload egress queue. that's the whole vibe. let's get into it π«Ά
β¨ NAME β¨
t4_ofld_eq_free β free an offload egress queue π«
like, literally the entire job description. no cap.
πΈ SYNOPSIS πΈ
int t4_ofld_eq_free (struct adapter *adap , unsigned int mbox , unsigned
int pf , unsigned int vf , unsigned int eqid );
it returns an int, bestie. five args. all of them matter. do not skip any of them, i'm begging π
π ARGUMENTS π
adapβ the adapter. the whole network card situation. the main character, honestly πmboxβ the mailbox to use for the FW command. yes, FW as in firmware. it's giving "talking to the hardware through the official channel" πpfβ the PF owning the queue. Physical Function energy π¦vfβ the VF owning the queue. Virtual Function energy. pf and vf are a duo, your honor β¨eqidβ egress queue id. the actual id of the actual queue. the whole point π―
π₯ DESCRIPTION π₯
Frees a control egress queue. periodt. that's it, that's the description π
lowkey iconic how short it is. the function does exactly one thing and does it well β very main character of it, ngl π
π SEE ALSO π
ok this list is long long. like, get a snack, get a drink, get comfortable π. every single one of these is referenced, no skipping:
the source file itself, first of all:
- Kernel file
./drivers/net/ethernet/chelsio/cxgb4/t4_hw.c

ngl if you read that whole list you deserve a little treat π. that's like a hundred functions. the cxgb4 family is huge and they all live together in t4_hw.c like one big chaotic group chat π§
